Depending on which company did the sorting, I am either 34% Northern Italian, 29% Northern Europe and British isles, and 6% other. 23 and me sez I am 51.5% Italian, 45.3% British isles, and some other, FTDNA says: 50% England, Wales and Scottish, Italian is 19%, and scandanavia is 18%, with a smattering of Malta and Ireland.
I say HA! They simply throw a dart and hope for something to work out.,
