there is a family of garzas from Lepe, SPAIN who have Jewish ancestry.The garzas in the late 1480's a small Judaizing clan of new Christians in Lepe.They fled to the canary Islands.The name Garza means heron. Many Jews changed there name to garza because it was an animal that according to Jewish tradition is Kosher to eat.Many Jews fled from the canary islands to Monterrey, Mexico because the inquisition was strong in the canary islands.They took ships from the canary island to Mexico.
