The table below contains the 25, 43 35 or 12 Y-chromosome DNA marker values for each participant in the project. Participants are identified only by Kit Number. The table also indicates the most distant known ancestor and his place of abode, for each participant.

There are currently 155 participants

So in summary, what questions can be answered.

Are McDuffies of Celtic or Norse Origin?

For most participants, the answer is quite clear, of the 42 separate bloodlines most are R1b Haplogroup, which in layman's terms means Celtic origin.  They would have come over from Ireland to Scotland between 1000 and 1500 years ago and prior to the last Ice Age would have occupied the Basque area of what is now Spain.  One McDuff or McDuffe is of R1a Haplogroup which can be termed Norse Origin.  They would have come from Northern Scandanavia around 1,200 years ago.  As the glacial ice sheet receded 11,000 years ago, they moved up from an area between the Black and Caspian Seas into Scandanavia.  Another McPhee is of I Haplogroup which inhabited the area which is now Croatia around 11,000 years ago and also migrated up through Scandinavia as the ice receded.  Two McPhees are of J2a, and one Duffy is of J2 Haplogroup which was found in the Middle East  until about 8,000 years ago when they moved in several directions including into Continental Europe.  Map 2 on the following link shows the migration of R1b, R1a and I Haplogroups and Map 3 shows the migration of the J2 haplogroup http://www.dnaheritage.com/masterclass2.asp

How many separate bloodlines are there?

Forty two so far.  One bloodline is the modal (most numerous) bloodline, and this is likely to be one of the older or oldest lines as it has a considerable spread.   This has been designated group1.

Do McAfees and McPhees show a common ancestor?

We now have McAfees who have a common ancestor with McPhees several groups.  Both names were originally rendered like McDuffie phonetically.  The name differentiation indicates that ancestors spent time in Ireland and are Scots Irish.

Do McPhees from around the world show a common ancestry in Argyll?
