Clan Donnachaidh DNA Project - Results

Visit our new project website at for much more information on the Donnachaidh DNA Project and results.

We now have over 800 participants in the Donnachaidh DNA Project. Many new connections have been made between men who before testing did not know of one another. The Duncans are coalescing into some well defined subgroups and the Robertson's and Reid's have started to do the same. We now have three cases of different Duncan groups jumping the pond back to Scotland. We now have confirmed three Scottish matches for these Duncan male lines in the US. These men share the same Y-DNA male line and it leads back to Scotland:) Results are divided by surname and haplogroup.
