Dec 17, 2007: Win some? Lose some?

Well, I'm not sure if this DNA result is going to add or subtract people from the family tree!
The final link to Archibald FAIRBAIRN and Alison CROSSER from one side of the test results is an unproven link, based purely on date/place proximity and naming patterns of the children of Archibald FAIRBAIRN and Janet SCOTT. I've reviewed this in light of subsequent research on the chap I believe to be the DNA match. On balance I still think it looks and feels right in the absence of any evidence to the contrary.
Any other FAIRBAIRN descendants out there to help confirm this? I've not traced any of the other lines from Archibald and Alison down to present day, so am short of candidates at the moment, but it would be fantastic if someone else would participate in the FAIRBAIRN Surname DNA project to aid these conclusions.
A male FAIRBAIRN descendant of Walter FAIRBAIRN and Agnes ROBERTSON would be great, or if anyone has a James, John or David born mid/late 1790s around Morebattle....
My research to date peters out before living people, the nearest candidates I currently know of would be children of:
Archibald FAIRBAIRN and Charlesina PHIMISTER, or their son Archibald (born Glasgow, died Jersey) who married Agnes Watt Gladstone FYFE.
Henry FAIRBAIRN and Emma Maud HANNEY, living Hampstead in 1901, with a 1 yr old son Stanley.
Walter Edward FAIRBAIRN and Davina Oswald MacDONALD: son Henry Edward F. was living in Edinburgh in 1930 when father died.
Walter FAIRBAIRN and Elizabeth ROY: two sons still alive in 1901 (Haltwhistle, Northumberland), a Walter and a John

If the other side of the match is who I think he might be, his email didn't bounce, BUT I think he died back in March.
However, researching this chap's family took me back from California to Melrose, and to Whitsome and Hilton, Berwickshire, and another Archibald FAIRRBAIRN, the one married to Mary GIESSEN. The two Archibalds are of an age, and having simultaneous families, so cannot be one and the same people. Both have sons named Archibald, one is my Walter's younger brother, so at least 2nd son in my family's case, but likely to be the first son in the other family.
My current theory is therefore that these two Archibalds share a grandfather via brothers Walter and Archibald, who will likely never be found, more's the pity.

Wonder what the rest of the results of the DNA testing will show up? All very exciting to find a match so quickly, and with only one participant!
I will update the Patriarchs page of the DNA project with a lineage of the second Archibald shortly, and possibly include some notes on my site's FAIRBAIRN page.
