Archibald Fairbairn

     John Fairbairn (m. Bessie fflint) is likely to be the family patriarch for the families of Archibald? Fairbairn, Robert Fairbairn, Archibald Fairbairn, Archibald Fairbairn, William Fairbairn (m. WANLESS), John Fairbairn and William Fairbairn.
The Archibald with the ? after his name has to have existed, as the Fairbairn Surname DNA project provided a DNA match between a descendant of Archibald Fairbairn and Alison Crosser, likely first son Archibald born Whitsome, Berwickshire, and a descendant of Archibald and Mary Grierson/Giessen's, son George, baptised Bowden, Roxburghshire. These two families are contemporaries in time and fairly close by place.
The name Archibald? is assigned as father of the Archibald who married Alison Crosser from my assumption that the 1783 baptism of an Archibald to an Archibald, hynd of Whitsome Vaults, is their likely eldest child.
Prompted by this unexpected success I researched the other Archibald and have now convinced myself that his father was Robert, and grandfather John (marr. Bessie fflint), this all being from both naming patterns of the children, and the baptisms being in the right area and timeframe as there are no convenient wills left around for us to find. The extended family also end up in all the right places (Smailholm and Kelso). There's even an Archibald as a witness to one of the baptisms, and a Thomas Anderson.

My calcs are that a grandfather to the two known to exist Archibalds would cover 8 generations in total, between the matching y_DNA candidates. This agrees with the 90% probability calculations from FamilyTree DNA's y_DNA calculations (95% that it was no more than 10).
This seemed good enough reason to join the families up in this way, it may however be a generation, or two, further back - until we also factor in the growing number of autosomal dna matches bewteen the two lines. (although subsequent BigY testing shows all tested candidate lines "meet" at a branch of the yDNA tree of mankind with an estimated formation of around 1725 - very conveniently about when John and Bessie married.)

The Fairbairn surname dna project has come up trumps - again.
I began to suspect that the family of FAIRBAIRNs I was tracing around in Ontario and Alberta just might belong to the family of an Archibald who married Jane Blakey in Tynemouth in 1841. Much later, I realised that I'd never actually checked this marriage cert. When this was remedied I was very interested to see that this Archibald's father was another Archibald.
Given that the one married to Jane was given as born about 1813 in Scotland in most available records, and the only Archibald son of Archibald I had in my database of Fairbairns was the one baptised in St Boswells in 1813 to Archibald F. and Janet Scott, it was looking even more likely that I'd found out what had happened to this latter Archibald, albeit that the father was shown with an occupation (gardener) that I hadn't associated with him. (Up till now I had assumed he had died prior to the 1841 census).
Thanks to a McKee researcher connected to the Ontario branch of these Fairbairns (who only knew their ancestry back to the Robert who married Martha Almira Huston), a descendant was convinced to represent his line in the Fairbairn dna project.
The preliminary results (Apr 2009) showed a 12/12 match, and by May they showed a 64/67 match, with the known descendant of Archibald and Janet (Scott) Fairbairn. QED, especially as two of those markers are unique in the project to this line, and marker cdya of 36 is shared with Martin the known descendant of Archibald and Janet (Scott) F, and none of the others in the project.
And when in Apr 2011 Ed turned up a military record for John, son of a Walter of Roxburghshire, which clearly showed his mother as Agnes ROBINSON, we finally had a proven representative of Archibald and Alison (Crosser) Fairbairn to compare the other representatives with. A good match.^7,8
