The Strain
Surname DNA Project was originally organized to determine whether two lines of
American Strain families—that of Thomas Jefferson Strain and that of John
Strain of Washington County, Tennessee—were related or not. The project has since expanded to include
other Strain families in

The
original participants selected Family Tree DNA (FTDNA) of
While most chromosomes are shuffled around from one generation to the next, the Y-chromosome is passed with little alteration down the male line of descent, from father to son to grandson, etc. So when males of the same surname are tested it is possible to determine whether they might have descended from a common male ancestor by comparing these selected markers on their Y-chromosome.
However, periodically mutations can occur which cause subtle changes in the Y-chromosome. The enzyme responsible for “copying” DNA may add or leave out one or more repetitions of a particular DNA sequence, or environmental factors may cause a mutation. Currently Family Tree DNA estimates that one mutation occurs, on average, about every 500 years or about 20 generations, although some markers are believe to mutate somewhat faster and others somewhat slower. These mutations are passed on from father to son. Though the mutations are infrequent they are unpredictable, and it is even possible for brothers to have slightly different Y-chromosomes.
Because it is not possible to accurately predict when these mutations will occur it is impossible to accurately determine the exact relationship of two individuals based on their DNA results. Their interrelatedness can only be stated as a probability. But the more similar the results are to each other the more likely it is that the individuals shared a common male ancestor in the more recent past, while the more different they are the more likely it is that the common male ancestor was more remote in time.
(For additional information on Y-DNA testing, go to www.familytreeDNA.com)
The following table shows the results of the Y chromosome DNA tests that have been processed so far by Family Tree DNA.
We assume (1) that the selected markers are dependable indicators of common ancestry, (2) that the test results are valid and no samples were contaminated, switched or misread, and (3) that all participants are actually descendants of the ancestors they claim.
Each column labeled DYS# refers to a particular marker on the Y chromosome. The numbers in each column are the number of DNA sequence repetitions (STRs) found at that marker. Family Tree has used these values to predict each individual’s Haplogroup, although it is necessary to test other slower-mutating snippets of DNA to confirm the Haplogroup. Haplogroup is useful in determining where in the world an individual’s ancestors might have lived—for example, R1b indicates Western European origins.

(Note from Family Tree DNA: It is obvious from our observation of 1000's
of samples that some markers change or mutate at a faster rate than others.
While that actual 'faster rate' has not yet been definitively calculated, not
all markers should be treated the same for evaluation purposes. The markers in red have shown a faster
mutation rate then the average, and therefore these
markers are very helpful at splitting lineages into sub sets, or branches,
within your family tree. Explained
another way, if you match exactly on all of the markers except for one or a few
of the markers we have determined mutate more quickly, then despite the
mutation this mismatch only slightly decreases the probability of two people in
your surname group who match 11/12 or even 23/25 of not sharing a recent common
ancestor.)
According to FTDNA, a one-step difference in a single marker (or “genetic distance of one”) indicates a 50% probability that these families shared a common male ancestor within 18 generations, and a 95% probability of a common male ancestor within 52 generations.
Many
of these test results are similar to the so-called Niall of the Nine Hostages
DNA signature, as shown below:

This
DNA signature is similar to that of several other surnames originating in
We believe that the more participants we have in this project, the clearer the picture will become as to who was related to whom. So all male Strains—or males with similar surnames, such as Strahan or Strachan—are encouraged to join the project.
The cost of the 25-marker DNA test from FTDNA is $169, plus a few dollars more for shipping. If you would like to join the Strain surname project, click on this link:

Please be aware that unless you are a Strain male the results of Y-DNA testing will not be meaningful. The Y-chromosome is not passed to females, so even if your mother was born a Strain you will not have received the Strain Y-chromosome from her. You may instead want to consider instead the mtDNA test, also available from Family Tree DNA, which examines genetic material passed from the mother to her children.
