I'm no expert on these topics, but I thought those reading this thread
might be interested that yesterday Israel's influential Haaretz
newspaper published an article about the genetic genealogy of
Portugese Jewish ancestry.

The de los Santos Coy line is from Lepe Huelva (coming to Saltillo in 1632) and shared genetics is in Southern Portugal and shows a Iberian Sephardic match. The book the Jews in New Spain states "After 1492, and to a greater extent after 1580, Jews traveled back and forth between Portugal and Spain".
