19th: Most Recent Common Ancestor

Found this table on the FT DNA site which shows a bit more about the likelihood of where the matched ancestors are: Probability for Most Recent Common Ancestor (MRCA)
Which makes it seem quite likely that our two matching results might share a common grandfather back from the contemporary Archibald FAIRBAIRNs.

18th: 2nd project member

The mystery match confirmed as a descendant of Charles and Mary (BATE) FAIRBAIRN, and has joined the project.

17th: First full 37 marker results in

First full set of results received. The 12/12 match (between descendants of Archibald and Janet (SCOTT) FAIRBAIRN, and Charles and Mary (BATE) FAIRBAIRN was also 25/25 but 36/37. See Results page for more details. Which is all very exciting, given this was completely unexpected, but certainly indicates previously unknown, and unfortunately unprovable via records, connections between Roxburghshire and Berwickshire FAIRBAIRN families.

13th: First results, first match

First set of preliminary results received, AND we have a 12/12 match with someone else in the FamilyTreeDNA database, unknown to me, and although the email hasn't bounced, it also hasn't been replied too. I'm guessing that his ancestors are Charles FAIRBAIRN and Mary BATE via their son Thomas Purdie FAIRBAIRN, and I would love to confirm this, and find out more as I know of now connection to this family - as yet.
