Okay, but the question is how would DNA differ between a Sephardic Jew who was born in Valencia and someone born in Genova from one or both parents of Sephardic Jewish background? They don’t just say he had Spanish and Jewish ancestry, they say he was born in Valencia, despite the previous most widespread theory that he was born in Genova.That’s what intrigues me.

I might be missing something here, but how would a genetic study prove where he was born? I see how it could prove Spanish and Jewish ancestry, but how does it show that he was the immigrant and not his parents? Beside, they even say he was born in Valencia… Awfully precise. And they’re quoting a documentary rather than a research paper…
