Our family DNA is interesting. We are able to consistently trace the family line back to the point of immigration for most cases, and usually our people came over in the 1600's. So we know what countries they came to the US from -- England, Wales, Scotland via Antrim, and the Rhineland. But when we look at some of the admixture breakdowns on GEDMatch, we get this consistent percentage of Italian showing up. It is in the neighborhood of 10%, va bene!
I am pretty sure the Templars are to blame. I told my daughter, "Your fantasy DNA is half Jedi, a quarter Gambler, and a quarter Scientist. The reality is more like a quarter Moisture Farmer, a quarter Orphan Scrounge, and half Sith."
