My last name is Scottish. The further back you research the purer the ancestry but as you get closer to yourself it’s more mixed. We come from all different ancestries especially in this country. We’re such a melting pot. We’re not perfect. But we integrate, we meet people from other ancestry. They marry and by the time you go down a few generations, you’re from everywhere!
On my father’s side, I think they came from England through Canada. It was quite common. There used to only be a few ways into this country, Ellis Island and through Canada. My father’s side settled in Canada for at least 2 generations and then migrated to the USA. – Rob
