5. FTDNA seems to underestimate British Isles, as mine turned out too low also

They got my Italian half correct showing Southeast Europe- 37%/Asia minor-8%/Iberian-3%,Sephardic-1%.

However, my other half which they estimate 17% British Isles and 34% Western/Central Europe is definitely wrong. Correct amounts should probably be reversed as I know my ancestry going back over 400 years under most lineages with the majority from England, Scotland and Ireland and rest from Netherlands and Sweden who all came to northeast.

I also tested on Ancestry and their test result was closer to what my documentation shows, with 33% Great Britain and Irish and the rest a mix of mostly Western Europe plus traces of Scandinavia and Eastern Europe.

I did find that several ancestors who immigrated to America in 1600's from England had parents who came to England from what is now Belgium or France, so that might have something to do with why FTDNA's estimates are heavier weighted to Western Europe vs British Isles.

The other website I have have imported my DNA to is Gedmatch which is free and has some interesting analysis tools, which seem more accurate than either FTDNA or Ancestry in estimating ethnic origins.
