No-If I ever have extra money to play with again, I want to get one of those kits from NatGeo and send in a cheek swab to find out. Since the traceable records stop at the area of Spain they came from, and the passenger manifests of ships, it probably doesn’t hold many surprises unless they can trace a it further back-then it probably just leads to the Romans.
Maybe not. My cousin has found that most old Texican families have native american mtDNA. The Spaniards mainly married local gals. Not very many brought their own wives and daughters along. She’s got south american origin mtDNA and her dad had north american mtDNA.
I suspect any Y chromosomes do probably trace back to Europe though.
