1 November 2004: This DNA Note is illustrative of the uses to which DNA evidence may be put in Family History Research by genealogists. The Strong,, DNA Results page: has been updated with the addition of results for Kit #24614. These results give some very interesting clues for use in further research, and are of particular interest to researchers of the Scots-Irish lineages of Counties Antrim, Armagh, and Down; and to certain of the New Jersey and Vermont lineages in the US.

For a number of years a researcher posted messages on the Rootsweb Strong List, persuing paper research of the family history of Samuel Beaman Strong, of Morris County, New Jersey. She had found evidence his father was a Presbyterian minister, born in County Down, Ireland, c. late 1700's. She was at a "brickwall", unable to connect with any of the other Strong lineages, but had some indication that the family had sojourned in the State of Vermont. See the following messages in the Rootsweb Strong List Archives from 1997:

The present researcher in  Kit#24614, whose husband is also descended from Samuel Beaman Strong; having previously shared info with the earlier researcher mentioned above, was also at a brickwall. They elected to join the DNA study, with results as posted. The DNA results eliminate possible affiliations with the New England Strong family and the Strangs of New Jersey. They match perfectly with the first three kits in the so-called "Tynan Abbey Assumed Haplotype".

Within the "Tynan Abbey Assumed Haplotype" there appears to be a mutation at DYS391=11vs12. At this point it is not yet possible to isolate when the mutation occured. However, all six of the "Tynan Abbey" kits are probably related and seem to be descended from a Scottish Strang lineage which migrated from Scotland to Ulster in the early 1600's. There are some background discussions found in the following references:
DNA Note #11.
DNA Note #14
The Tulliniskey Discussions
As a side note, there is some speculation the possible forebearer identified in the Tulliniskey discussion, Cuthbert Strang, may be a descendant of Robert, AKA Cuthbert, Armstrong. Resolution of that possibility will have to await further DNA testing and other paper research.

30 January 2008:   Reference to the Armstrong DNA Results page at will show that to date, no Armstrongs have been found who match the Tynan Abbey lineage, nor indeed who match any of the various “Strong/Strang/LeStrange, etc.,” lineages.    However, we now have a new Strang participant whose results in Kit#106170 match the Tynan Abbey Stronge haplotype.   See the Strong/Strang/LeStrange DNA Results page:   It will be noted that Kit#106170, who traces his ancestry to Lanarkshire in Scotland,  exhibits DYS391=11, in common with four of the other six kits in the group.   This MAY suggest that Kit#6256 and  Kit#6386, exhibiting DYS391=12, reflect a mutation which occurred after migration from Scotland to Ireland.    That might be confirmed if additional testing of Scottish Strangs fails to produce any members exhibiting DYS391=12.   Further testing results are expected from Kit #106170 which may affect evaluation of the match.   If the match continues to hold good through the expected additional markers, we now have an important clue concerning the origins of this line of Strang/Stronge/Strong participants.   Consultation of John R. Mayer’s book, “Strange of Balcaskie”, may yield some further clues concerning the Lanarkshire ancestry of the lineage.    These results also tend to confirm that the roots of the Tynan Abbey lineage are distinct  in Scotland or the Borders from that of the chief Strange of Balcaskie lineage also displayed on the Strong/Strang/LeStrange DNA Results page:   

1 November 2004:   The match of results in Kit #24614 with the other "Tynan Abbey" results perhaps offers a clue which may help the various researchers in their further persuit of the ancestry of Samuel Beaman Strong. Refer to the pedigree chart for Kit #24614 and note the reference to the particular discussion concerning the family of William Strong of Fayston, Vermont, and Tanderagee Townland, Co. Armagh, Ireland: There are some tantalizingly close similarities in the family history of the two lineages under discussion. Both involve discussion of 1) a Samuel Strong; 2) ministries with the Presbyterian Church; 3) contacts with Vermont; 4) origins in the Co. Down, Ireland, vicinity (Tanderagee, Co. Amagh, adjoins present day Belfast in Co. Down). There are some facts that don't seem to match... the generations appear to be off by one, and there is a confusion factor involving the marriage of Samuel Beaman Strong to Susan Casterline, and mention of Samuel Strong of Fayston, VT's marriage to Ann Black. Further paper research may resolve these conflicts... but it looks like there is a good possibility of affinity between the two lineages.

A possible resolution of the conflicts noted above would be that William Strong who married Margaret, and is represented in Generation #7 of the pedigree chart for Kit #24614 had three sons, Richard, Samuel, and John. Samuel is the progenitor of the Fayston, VT line; and John is the progenitor of the lineage including John's son, Samuel Beaman Strong. DNA testing of a member of the Fayston, VT lineage might help to confirm the affinity... and the respective researchers may be able to compare information which will help resolve their respective brickwalls, and further add to the fund of knowledge concerning the overall Antrim and Down Strong lineages.
