Clan MacMillan Y DNA Project Publishes Dendrogram of Test Results

Dec 6, 2022

A graph of the results of the Clan MacMillan Y DNA project to demonstrate the various groupings and branching of the Clan MacMillan. A more detailed version that includes the Most distant known ancestors of the participants (those that have chosen to share that info) is found on the MacMillan Project page at However, this is only available to the participants.

We invite all MacMillans to join us. Ladies can participate in the YDNA project by having a male McMillan relative test, a father, brother, cousin, since only males have a Y chromosome, and it is only passed down father to son.
