Alexander Blair - Jane Scott

BLAIR DNA Project

Alexander Blair & Jane Scott/Janey
James Blair & Catherine “Kitrin” King

There has been and continues to be controversy as to whether the James Blair who married Chatherine "Kitrin" King is the son Alexander but there is ongoing research by many folks and developments should be watched. The possibility that this James is the son of Alexander is based on several speculative facts which are presented in the "Blair Society for Genealogical Research Members’ Lineages (1983 - 2003)".

The DNA test results from the three participants who believe they descend from Alexander and Jane Scott provide strong evidence that James Blair is in fact the son of Alexander.

Two participants (#7277 and #7933 claim to descend from Alexander Blair and Jane Scott through James Blair and Catherine King. They both descend through Josiah Blair, son of Robert and Mary Polly Bean, son of James.

A third participant (#66626) descends from Alexander Blair and Jane Scott through John Blair and Jane Robertson. John is a known son of Alexander.

All three participants are an exact match on 25 markers.

The actual marker values for each participant are shown in the table below. FTDNATiP™ estimates an 80.9% probability that these participants share a common ancestor within 14 transmission events (the number of transmission events between #7277 and #66626). Given the DNA test results and conventional research, it is almost certain that all three participants do descend from Alexander Blair and Jane Scott.

The level of confidence would increase if #66626 were to upgrade to 37 markers and continue to match #7933 who has already tested 37 markers.

The table below shows the test results for all three participants.
