John Fairbairn 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.
An additional line joined this extended Fairbairn family with an unexpected match between these Archibalds and a descendant of William
Fairbairn and Jean
Wanless, who had emigrated to Quebec. This 67/67 match between a descendant of the Archibald who married Mary
Grierson, and a descendant of William
Fairbairn and Jean
Wanless. and the 64/67 match between the
Crosser line and these two lines has led me to join up the families as per the linked charts.
