Below are the known genealogies of the 37 marker participants. There are some interesting PLACE tie ups which currently do not correspond with DNA, but of course a place can have different branches of the 'family' in it - as we showed in the 1787 children list for Balquhidder parish, printed in the CGS Newsletter 50. Further comment appreciated!
Brief notes on the earliest known ancestry of DNA participants: if there is no information listed, then I have not been given it at this point.
The order follows the updating chart which is the Family Tree DNA public web site for the MacGregor project. Unless otherwise stated, all places referred to specifically in the text are in Scotland.

27811 descends from James Grigor born in 1771: his parents may have been John Grigor and Janet Duff of Monidie, but it is difficult to connect, with certainty, from one generation to the next in the old parish registers. In 1804 James married Rebecca Richardson in the neighbouring parish of Redgorton. They had 5 children: John (1805), Isabell or Bell (1807), Jannet (1811), Gregor (1814) and Joseph (1818) all baptised in Monidie. James died in 1818 before the birth of Joseph.

At first the family lived in Dunkeld in a cottage called Tully Mully.
[Comment: the DNA correspondence between 27811 and 2726 suggests that they share a common ancestor, presumably the father of Alexander MacGregor ancestor of 2726 or one of his immediate ancestors].
