Here is the "Conservative" estimate of his genetic make-up : 97.1% European and 2.9% Unassigned.
These results were consistent with the paper trail genealogy, though I found the 0.1% Finnish interesting, as well as the 0.6% nonspecific Southern European.
Here is the "Standard" estimate of his genetic make-up : 99.4% European, 0.5% Unassigned and 0.1% South Asian.
Now where that South Asian comes into the family tree I have no idea as there are a few branches that haven't been traced. There is a larger percentage of Southern European in this estimate as well.
Here is the "Speculative" estimate of his genetic make-up : 99.7 European, 0.1% South Asian, 0.1% East Asian & Native American, and 0.1% Unassigned.
The 29.3% British & Irish and the 17.1% French & German make sense considering how many of his lines I've been able to trace to those areas of Europe. The 5.5% Scandinavian and 0.3% Finnish, as well as the 1.7% Italian and 0.9% Iberian indicate lines that I haven't established a paper trail.
The most interesting is the speculative 0.1% Native American - there is no tradition or evidence found of any Native American in my dad's lines, and the South Asian - which 23andMe indicates India or Pakistan is totally new to me. Will have to see if I can get other members of his family to test and see what percentages show up.
