A. INTRODUCTION AND SUMMARY
DNA analysis as a genealogical technique first became practical for amateur
researchers about four years ago. But so far, it has been used only by a tiny
fraction of the millions who pursue genealogy as a hobby. In fact, it is probably
safe to say that the overwhelming majority of family researchers still regard
DNA testing as a mere curio -- to the extent they even know about it.
On the other hand, DNA analysis has already contributed positively and impressively
to research on the large and widely dispersed Brown family descending from William
Brown of colonial Augusta Co VA and early Knox Co TN.
The related groups in this large extended family have ranged from the Browns
of Warren Co TN and St Clair Co AL; to the Browns of Pontotoc Co MS, Izard Co
AR and Marion Co AR; to the Missouri and Kansas descendants of Gideon Leeper
Brown; and to the descendants of Oregon Trail pioneer Hugh Leeper Brown, founder
of the town of Brownsville, Oregon.
Beginning in 2002, DNA "surname tracing" has been used not only (1)
to locate and confirm relationships among descendants of this family, especially
in cases where the paper trail has been incomplete, but also (2) to show that
certain relationships previously hypothesized are in all likelihood not valid.
In brief, the DNA tests enumerated below have advanced considerably our understanding
of relationships between and among descendants of the William Brown in question.
At the same time, it is important to realize that these findings have assumed
their importance almost entirely within the context of a large body of traditional
genealogy conducted by numerous researchers for this kinship group since at
least the early 1960s.
In the author's opinion, the import of the DNA findings -- taken in essential
conjunction with traditional documentary research -- is that there can no longer
be any reasonable doubt as to the very close relationship of these scattered
families, even though precise "paper trails" between and among them
have not in all cases been satisfactorily documented with the sorts of primary
sources that customarily have formed the backbone of serious genealogy.
Moreover the author submits that, in addition to their obvious benefits for
research on the Brown family of this website, these DNA results and their
interpretation can be a useful case study for genealogists working on other
family lines, especially in the way that these results have both sustained
and falsified hypotheses drawn from traditional genealogy.
B. TECHNICAL DETAILS ABOUT DNA
Most DNA analyses for genealogy have so far involved tests of the Y chromosome.
This "yDNA" is possessed only by males, and it is passed from father
to son over hundreds of years (and even thousands of years) with little or no
change. As such, yDNA "traces" the surname in a fashion virtually
ideal for genealogy. [1]
For basic "surname tracing" (which describes the methodology
used for research on this website's Brown family) numerical yDNA scores
are compared to determine if two or more living men share a recent common ancestor
in their unbroken male-to-male lines. If the men in question have yDNA numbers
that are identical or very close, then basic techniques of statistical inference
may be used to estimate the probabilities that their common ancestor lived within
a given number of generations.
So for example, if two identically surnamed men should match perfectly on 23
or more markers from the commonly used 25-marker DNA test, then one could have
a high degree of confidence that their common male ancestor lived within the
last few hundred years.
If on the other hand the two men in question should match on fewer than 23 markers,
then it is highly likely either (1) that they do not have a common "male
line" ancestor, or (2) that their common ancestor lived so long ago as
to render "genealogy" -- as that term is commonly understood -- virtually
useless for identifying him.
It is beyond the scope of this brief discussion to deal with the complex matters
of genetics and mathematical statistics that sometimes arise when DNA science
intersects with old-fashioned genealogy. Suffice it to say, however, that the
simple and relatively powerful "yes-no" analysis described in this
article represents only a first step along the new path of DNA genealogy. [2]
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
The following sections will discuss in detail the specific DNA matches and "non-matches"
that have advanced significantly the genealogical research for the extended
Brown family of this website.
C. THE FIRST BROWN DNA MATCH
Y-chromosome DNA testing was first used for genealogical research on our Brown
line in mid-2002, when Vic Brown of Denison TX and Jim Brown (the author) both
submitted DNA samples for testing under auspices of the large Brown/Browne/Braun
DNA Study, an activity conducted by amateur genealogists via a contractor, Family
Tree DNA Inc. of Houston TX, with actual lab work at the University of Arizona.
[3]
Vic and Jim each had submitted his own DNA in complete ignorance of the other
man's test. They had communicated once, about a year earlier, since they knew
their Brown ancestors had lived near one another in early Warren Co TN. But
they concluded that given the total lack of direct evidence on point -- evidence
which had been sought by Brown researchers for years -- there was no realistic
chance of either proving or disproving a relationship between their Brown lines.
Then about a month after the samples were submitted, Vic and Jim got the unexpected
news of a perfect 12/12 DNA match. To make a long story short, the odds against
such a match were huge -- unless of course their Brown ancestors in Tennessee
actually were close kin. And as such proof of kinship, the DNA match took a
large chink from the "brick wall" that had long blocked research by
descendants of the Browns of St Clair Co AL, several of whom in the 1960s had
traced their line to Warren Co TN (but no further).
Shortly before Vic and Jim discovered their surprising DNA match, and completely
unbeknownst to them, fellow Brown descendant James E. Hargraves of Elk Grove
CA had become convinced that his and Jim's mutual ancestor David Brown was closely
related to a large family of Browns including not only the Revolutionary War
veterans Thomas and Robert Brown of Warren Co TN, but also several clusters
of Browns in pre-statehood east Tennessee and in 1820s Arkansas Territory.
So although Vic and Jim had been totally unaware of their kinship, their DNA
match came to James Hargraves less as a surprise than as a powerful confirmation
of relationships he had recently proposed (or "hypothesized" -- although
he did not use specifically this word) as a result of his work in traditional
"paper" genealogy. [4]
And while Vic did not have flawless documentation back to his likely ancestor,
Revolutionary War vet Thomas Brown, Vic's and Jim's DNA match taken together
with all of James Hargraves' exhaustive evidence and previous conventional genealogy
left little or no doubt that their Brown ancestors were indeed from the extended
Brown family of Warren County's well-known Revolutionary War veterans, the brothers
Thomas and Robert Brown. Moreover, since these brothers had a solid paper trail
back to Augusta Co VA, the findings were sufficiently persuasive in the author's
opinion to carry the genealogy of his St Clair Co AL Browns all the way back
to the same spot in 1750s colonial Virginia.
D. THE SECOND BROWN DNA MATCH
The next instance of DNA testing for our Brown line was the discovery in 2003
of a 12/12 match between Danny Brown of Branson MO and Vic Brown, together with
a 24/25 match between Danny and Jim Brown. Danny is a documented descendant
of the Thomas Brown who died in St Clair Co AL in 1819. [5]
Before Danny's DNA test, James Hargraves had proposed on the basis of circumstantial
evidence that this Thomas was a brother of David Brown. Danny's DNA results,
on the other hand, constituted direct evidence of close kinship between Thomas
and David Brown -- evidence that had the additional virtue of being consistent
with (and supportive of) a belief in their having been brothers.
In conclusion, although Danny's DNA results also are consistent with "cousinship"
between David and Thomas Brown, it is the author's opinion that unless and until
contrary evidence should appear, the most plausible scenario is one of siblingship
-- so that James Hargraves' interpretation has been entirely appropriate in
positing the two men as brothers
E. THE THIRD BROWN DNA MATCH
Most recently (June 2004) a DNA test with John Pershing Brown of Manhattan KS
has revealed a 25/25 match with Danny Brown, a 12/12 match with Victor Brown,
and a 24/25 match with Jim Brown. [6]
John is a descendant of Gideon Leeper Brown, whose family went more or less
directly to Missouri from east Tennessee in the mid-1800s, without ever having
resided in Warren Co TN. The upshot is that John's DNA match has been critically
important in validating James Hargraves' proposal that the unusual name "Leeper"
(chiefly as a middle name, but also as a surname) is a key for establishing
relationships among a widely dispersed group of Brown families, who have by
now been traced all the way from Virginia and the Carolinas to Tennessee, Alabama,
Mississippi, Arkansas, Texas, Missouri, Kansas and Oregon. [7]
F. FOUR NON-MATCHES AND THEIR IMPORTANCE
No discussion of DNA genealogy should leave the impression that positive "matches"
are the be-all-and-end-all for this new type of research. In fact, to the extent
that genealogy borrows from well-established scientific methodology, then an
ability to falsify proposed relationships ("hypotheses") is fully
as important as "proof" -- whatever one's definition of the latter.
[8]
In this regard, it's worth noting that in at least three recent instances, DNA
tests have shown at high levels of statistical confidence that certain Brown
lines with roots in early Warren Co TN or St Clair Co AL were not kin to the
extended Brown family of this website.
In the first recent case, a DNA sample from a living descendant of the Absolom
Brown family of early Warren Co TN has shown these pioneers were almost certainly
not related to their neighbors, the family of the Revolutionary War veterans
Robert and Thomas Brown -- settling a question that had long lingered among
Brown researchers for the County. [9]
In the second recent case, a Brown-surnamed man with apparent roots in St Clair
Co AL was found not to match the family of Thomas and David Brown -- in spite
of the fact the test participant's ancestors had been listed in early censuses
as children of Thomas Brown's widow. [10]
In the third case, a descendant of Daniel Brown of early Warren Co TN was found
to have a perfect DNA match with a well-documented Brown family from neighboring
White Co TN, a line clearly not related to the Brown family of this website
-- in spite of a well-founded prior belief that Daniel Brown was from the extended
family of the Revolutionary War veterans Thomas and Robert Brown. [11]
In the fourth recent case, a Brown family from Jackson Co TN has been found
to have different DNA from the Browns of Warren Co TN -- in contradiction to
a hypothesized relationship between the two families. [12]
Finally, tests under auspices of the large Brown/BrowneBraun DNA Study have
already identified more than 80 separate Brown families with no genealogical
relationship to the extended Brown family of this web site. Many of these other
families, moreover, lived in early Virginia or the Carolinas -- the same general
vicinity as William Brown of early Augusta Co VA and Knox Co TN. So if nothing
else, the "negative" comparisons with these other families have narrowed
considerably the range of possibilities for finding kinship relations to the
William Brown line. [13]
G. SUGGESTIONS FOR FUTURE RESEARCH
Many puzzles concerning the Brown family of this website might eventually be
addressed by DNA analysis. Here are four examples:
(1) The single DNA test carried out so far with a man from the David Brown line
shows a very small mutation that is not present in the 25-marker tests for either
the Thomas Brown line of St Clair Co AL or the Gideon Leeper Brown line of Missouri.
Yet the two latter lines have identical DNA on the 25 markers in question.
[14] Given the limitations of currently available data, it is not
possible to determine whether this mutation arose with David himself, with his
father, or with one of David's descendants. But if this same mutation should
eventually be found in a Brown-surnamed man who is demonstrably not descended
from David, then the results almost certainly would falsify the hypothesis that
David and Thomas Brown of early St Clair Co AL were brothers -- and the same
results would simultaneously necessitate the alternative explanation that they
were cousins. On the other hand, if a test on a "non-David descendant"
should not have this particular small mutation, then the hypothesis of brotherhood
between David and Thomas would continue to be accepted.
(2) Settlers Francis Brown and Hugh Brown are mentioned prominently in the archives
of colonial Augusta Co VA, often in proximity to a William Brown and his probable
father-in-law, John Black. [15] Yet there appears little chance that conventional
paper genealogy will ever settle definitively the questions of whether Francis
and Hugh Brown were kin to the William Brown who died ca. 1807 in Knox Co TN.
On the other hand, if we should locate living Brown-surnamed men with good paper
trails back to Francis or Hugh, then DNA from these living men might either
confirm or falsify the hypotheses of kinship among Francis, Hugh and William
Brown.
(3) The will of William Brown, 1807 in Knox Co TN, mentions son John Brown.
[16] There are also numerous records from early Roane County (previously
a part of Knox) that show a John Brown as Sheriff, in close proximity to men
who appear to have been William's sons Alexander, Robert, Thomas and William.
[17] The author has encountered suggestions from other researchers that
John Brown the Sheriff may have been the same man as John Brown of the will.
But given all the men named "John Brown" in early Tennessee, the possibility
of settling this matter by conventional genealogy are slim at best. On the other
hand, an answer might be possible if a DNA sample could be obtained from a living
Brown-surnamed man with an unimpeachable paper trail back to Sheriff John Brown:
If this DNA should turn out to match that of our William Brown's descendants,
then we could not exclude the possibility that John was William's son. A non-match,
however, would almost surely lead us to conclude that the two men were from
entirely different Brown families.
(4) Two families in present-day Texas, who have not been able to document "paper
trails" to the Brown family of this website, have ancestors from Alabama
known to them respectively as "Guionell L. Brown" [18] and "Leap
Gian Brown." [19] Another Texas family has an ancestor reputedly
from St Clair Co AL, named "Francis Marion Brown." [20] In
all three instances, naming patterns and geographic proximity point to kinship
with Browns descended from William Brown of early Augusta Co VA. [21]
If living Brown-surnamed men from any of these contemporary Texas families could
be located for DNA tests, then it is very likely they would match the four Brown
men already tested. And if these Texas descendants should have minor mutations
away from the DNA "scores" of the previously tested men, then the
information might help eventually to establish a new picture of "branching"
patterns in the Brown family tree.
H. CONCLUSION
A large body of conventional "paper" research on the extended William
Brown family has been conducted over the past 40+ years by a number of descendants
and their kin. In this regard, the discovery by James Hargraves of the "Leeper
key" has been critically important, alongside prior work by a
dozen or so other kin with whom the author has shared information since he first
researched his Brown line in 1962. This number has included the late Marvin
Ryan, the late Lois Barrett O'Kelly, Judy Voran and others. [22]
Without this important foundation, the specific DNA matches and mismatches described
above would have had greatly diminished usefulness -- and apart from the initial
and totally unexpected match between Vic Brown and Jim Brown, they might never
have been found.
Likewise, without the rich body of "hypotheses" provided by this conventional
genealogy, it would not have been possible to articulate the suggestions above
for future research.
In the author's opinion, the upshot of the happy marriage between DNA analysis
and traditional documentary genealogy described above has been to
elevate from a "credibility based upon preponderance of the evidence"
to a "credibility beyond a reasonable doubt" the following propositions:
(1) that the author's great-great-great grandfather David Brown of
early St Clair Co AL was closely related to Thomas, William, Alexander and Guion
Leeper Brown of the same county;
(2) that these men were from the same family as the Revolutionary War veterans
Thomas and Robert Brown of Warren Co TN;
(3) that Gideon Leeper Brown of Missouri and Hugh Leeper Brown of Oregon shared
a common ancestry with the St Clair and Warren County Browns; and
(4) that all these men were from the line of the William Brown who moved
from Augusta Co VA in 1758 to the Waxhaws region of NC/SC and who died
in Knox Co TN ca. 1807.
Moreover, as a general matter, DNA science and the closely related field of genetics
can reasonably be expected to continue their rapid advances during years
to come -- in such fashion that the application of DNA testing to
genealogy can be expected to create an ever-improving methodology for both
amateur and professional researchers. Therefore all family historians, whether
or not related to the Brown family of this website, may justifiably hold an optimistic
view as to the possibilities for continued cross-fertilization between
the new discipline of DNA science and the old discipline of documentary
genealogy.

APPENDIX: A Speculation on
DNA and Hypothesis-Friendly Genealogy
The role of hypotheses and "hypothesis testing" in genealogy is a
subject in its own right that deserves much more exploration than possibly
can be provided here.
But since the new field of DNA genealogy has already borrowed insights and techniques
from the "hard sciences" of microbiology and genetics, it seems appropriate
here to discuss briefly how the scientific methodology of hypothesis
testing may be applied to genealogy -- including not only DNA genealogy
but also conventional "paper" genealogy, especially in cases
where the latter may depend upon circumstantial evidence.
In brief, although perhaps the issues come to the fore most clearly with the
example of DNA genealogy, the author believes all genealogy can benefit
from an "hypothesis-friendly" approach. [23]
A common dictionary definition of the word "hypothesis" (plural "hypotheses")
is:
"a proposition tentatively
assumed in order to
draw out its logical
or empirical consequences
and so test its
accord with facts that are known
or may be determined."
[24]
For purposes of the discussion here, a working definition of the term "genealogical
hypothesis" is taken then as a plausible but tentative explanation of a
kinship relation between or among individuals that has been put forth on the
basis of (1) logical reasoning, combined with (2) evidence that is either circumstantial,
or in the case of direct evidence, seriously incomplete.
It is obvious from this working definition that genealogical hypotheses are
nothing new. Researchers have always relied on them, whether or not explicitly,
and whether or not an identical terminology has been involved.
But it appears to the author that conventional genealogy has generally
tended to treat hypotheses somewhat as illegitimate children, not to be openly
acknowledged and not to be relied on for important research findings.
In contrast, the approach advocated here is based in part on a belief that waiting
for virtually flawless direct evidence can be counterproductive, by prematurely
closing off potentially fruitful avenues of research.
In other words, an hypothesis-friendly methodology is more willing than conventional
genealogy to use circumstantial evidence and/or seriously incomplete direct
evidence, so as to "connect the dots" in logical and plausible patterns.
Such patterns then may help not only to guide new research, but also may help
us discern previously unseen relationships whenever we take fresh looks
at old data.
In this view, a genealogical hypothesis is something to be sought and emphasized,
not only with caution as to its limitations but also with an
appreciation of its potential for advancing one's research agenda.
In many cases, this process can help bring about what one genealogist has usefully
described as an "interim analysis." [25] The interim analysis
may then provide a valuable framework for seeking, organizing, and interpreting
additional data.
And following upon the example of the hard sciences, an hypothesis-friendly
approach may be undertaken with the reasonable expectation that an interim analysis
often will evolve into a more broadly accepted interpretation -- moving in the
best of all cases from a tentative application based upon "preponderance
of the evidence," into an acceptance "beyond a reasonable doubt."
In author's opinion, the most useful research "advice" flowing from
an hypothesis-friendly approach to genealogy may be encapsulated as follows:
When faced with a genealogical "brick wall" (defined as the absence
of satisfactory direct evidence to support an essential relationship, without
which a particular research path comes to a halt), one should attempt to establish
one or more plausible hypotheses that serve as a tentative solution or solutions
to the problem at hand -- stated openly, with full acknowledgment of any logical
or empirical shortcomings. Then use these hypotheses to guide future research.
Any new findings should eventually be employed to test the hypotheses. If new
findings contradict any given hypothesis, the latter should be discarded without
embarrassment. But if new findings are consistent with a hypothesis, then it
may be held with greater confidence -- with the recognition that it will always
remain subject to additional confirmation or falsification in the face of new
evidence.
The methodology advocated here is not without its dangers. The reader is justified
in a certain apprehension that it may increase the ease with which unskilled
or careless genealogists jump to unsupported conclusions by misusing or misunderstanding
the "interim analyses" of conscientious researchers, no matter how
carefully the hypotheses may be hedged nor how cautiously the analyses may be
presented.
In defense, the author submits that the unskilled and the careless will probably
do their damage in any event, whether conscientious genealogists use, or whether
they avoid, an hypothesis-friendly methodology.
At the same time, one may hope that the explicit presentation of genealogical
findings as hypotheses, with forthright discussion of their ever-present logical
and/or factual shortcomings, will in the long run improve rather than degrade
our ability to combat erroneous genealogy.
An analogy to the Internet may be appropriate: Probably all experienced researchers
know today how the Internet has allowed unsupported and downright incorrect
genealogical information to spread with an ease and persistence that far exceed
comparable problems when genealogy was restricted to conventional printed media.
But just as the Internet's genealogical virtues overwhelmingly outweigh its
vices, it seems reasonable to suggest that a wider appreciation of hypothesis-friendly
genealogy can far outweigh the potential drawbacks.
Two important cautionary comments:
In order for findings derived from the hypothesis-friendly approach to
have credibility, there should be a clear explanation of, and an emphasis upon,
the inevitable limitations of the methodology and the inferences drawn with
its help.
Equally, propositions resting upon this approach should be presented in such
a manner that the reader will readily perceive not only that they remain open
to refutation in the face of credible contradictory evidence, but also that
the researcher proposing the findings is not "defensive" about their
being tested in the light of possible new evidence, since all genealogical findings
must to some extent remain tentative for all time. [26]
In the author's opinion, DNA analysis fits perfectly with hypothesis-friendly
genealogy, since -- as it is absolutely critical to understand -- a DNA test
generally cannot in and of itself "prove" a specific relationship:
Rather, the results of a DNA test may either be consistent with a hypothesis
that has been posited on the basis of some prior information, or alternatively,
the DNA results may falsify such a posited relationship.
The case of Thomas Jefferson and Sally Hemings is useful to illustrate why a
DNA test generally cannot "prove" a relationship: In the Jefferson-Hemings
investigation, DNA samples were taken from two living men, one a descendant
in an unbroken male-to-male line from one of Sally's sons, the other a descendant
in an unbroken male-to-male line of Thomas Jefferson's uncle, Field Jefferson.
The two DNA samples matched closely.
This result was entirely consistent with the hypothesis that Thomas Jefferson
was the father of Sally's son, since Mr. Jefferson's yDNA signature would have
been the same as that of his uncle. But the DNA test by itself cannot discriminate
between this hypothesis and the alternative explanation that one of the uncle's
sons, or Thomas Jefferson's brother or nephew, was the father of Sally's child.
[27]
Beyond this point, DNA testing per se has little or nothing left to contribute,
so that historians concerned with the Jefferson-Hemings matter must then fall
back upon circumstantial evidence -- derived almost entirely from conventional
"paper" documentation -- to decide which of the competing hypotheses
has the greatest explanatory power.
So as shown by the Jefferson example, and equally by the
example of the Brown family of this website, DNA genealogy's promise for
research on any specific family is most likely to be realized within a context
of plausible and well-organized hypotheses derived from conventional documentary research.

on the unbroken female-to-female line by means of mitochondrial DNA and (b)
so-called "deep ancestry" research. These two investigative modes
have not been used to study genealogy of the Brown line of this website
and so will not be discussed here. For information on these techniques, see

base of DNA results for ALL families carrying the Brown surname, not just the
family of this website. The study also includes families whose surnames
use variant spellings like Browne, Broun and Braun. Over 80 separate,
non-related Brown lines had been identified within the study by mid-2004,
based upon DNA samples from more than 100 living men, all of them believed
to descend in unbroken male-to-male lines from Brown-surnamed male ancestors.

opinion) that the wife of William Brown of early Knox Co TN was Martha Bassett,
this lapse does not detract from their value in tracing the Browns from
Tennessee to Missouri and points west.
8. The prevailing opinion among students of scientific methodology is that one
generally should not speak of hypotheses as being subject to "proof"
or as capable of being "proven." The favored terminology, rather,
is to speak of them as "not falsified" or "sustained" --
or similar words emphasizing that all hypotheses and indeed all scientific knowledge
are to some extent tentative, and therefore never "proven." See the
references in footnote 23. It is the author's opinion that genealogists should
follow a similar practice. On the other hand, the words "proof" and
"proven" are so often used in common parlance that any attempt to
banish them from genealogy obviously would be futile, especially since in 1997
the Board for Certification of Genealogists formally adopted the "genealogical
proof standard" to replace "preponderance of evidence" as their
chief test of credibility. See Christine Rose, Genealogical Proof Standard
(San Jose CA: Rose Family Association, 2001), p. 1; and, Board for Certification
of Genealogists, The BCG Genealogical Standards Manual (Orem UT: Ancestry
Publishing, 2000), pp. 1-2. On the other hand, the latter publication does acknowledge
"that any statement about ancestors, even if it meets the GPS, is not absolute
or everlasting." Ibid., p. 2. The author suggests that this caveat
is to some extent inconsistent with the Board's determined use of the word "proof."

23. A standard reference on the role of hypotheses in science is Karl Popper,
The Logic of Scientific Discovery (various editions). For a summary of
Popper's views and those of his critics, see http://plato.stanford.edu/entries/popper/.
"Popperian" methodology has been particularly influential in
the social sciences. See for example, Milton Friedman, "The Methodology
of Positive Economics," in Essays in Positive Economics (Chicago:
University of Chicago Press, 1953). And a Google search on "Popper and
sociology" yields about 21,600 entries. See also http://www.sociology.org.uk/p1mp4n3d.htm.
The author has not, however, located in print or on the Internet a systematic analysis
of the use of hypotheses in genealogy, although bits and pieces are abundant.
Perhaps the most definitive recent discussion of genealogical methodology is
Elizabeth Shown Mills, Evidence!: Citation and Analysis for the Family Historian
(Baltimore MD: Genealogical Publishing Co., 1997). Mills clearly recognizes
the important roles of hypotheses and their testing in genealogy, but she does
not present a specific analysis of the matter. Ibid., p. 47.

1973 edition.
25. The term is taken from Richard A. Clifford, "Tools Used in Analysis
of a Century-Old Genealogical Research Problem," reprinted from The
Genealogical Journal, Vol. 4, No. 4, December 1975, at http://freepages.genealogy.rootsweb.com/~turnbo/tx/pg82.htm.
The article describes how a hypothesis-friendly approach was profitably applied
to genealogical research on Clifford's Turnbo family, contrasting his "interim
analysis" with conventional genealogy's use of "direct evidence documents
... that do not require any reasoning process or inference to prove the family
relationship of two or more persons."
26. The Board for Certification of Genealogists states "that any statement
about ancestors, even if it meets the GPS, is not absolute or everlasting."
Op. cit., p. 2. So even though the BCG does not use the word "hypothesis"
in their Standards Manual, they have in essence acknowledged that all genealogy
is, in the final analysis, a series of hypotheses. And similarly, Elizabeth
Shown Mills states that "the case is never closed on a genealogical conclusion."
Op. cit., p. 57.
