A question about Sephardic Y-DNA. My dear, long-lost Cansino cousin could not understand why many of his Y-DNA matches traced their origins back to men from the British Isles with Anglo sounding names which he did not recognize. I told him about a geneticist who mentioned that Sephardic Y-DNA often comes from non-Jewish haplogroups. Could it be that a man from Asturias converted to Judaism and married a Jewish woman in the early Middle Ages? I began working on his matches and tracing back their paternal line, which led me to a Jacob Sunderlin in Scotland, a man named Southwick married to a Rachel Mosher, a Nathan Cooper Fish and a Jewish merchant (also from Scotland) named Robertson. All of them were living in the British Isles in the mid-1700s. I also traced a Chilean match to a man from the Nunes Vas family. Which makes sense because I have several matches with people who descend from the Senior Coronel family, which in turn was related to the Nunes Vas family, among others.Did the Cansino come from the British Isles and settled in Asturias, or was it the other way around? I was under the impression that the Jews settled in the north of Spain before the Reconquista had arrived there from Andalusia after the Muslim invasion in 711. When did Jews first settle in England? Forgive my ignorance!
