I received an e-mail from a NMGS member who pointed me to a Smithsonian Magazine article about possible crypto-Jews in Northern New Mexico and Southern Colorado. I don't wish to enter the debate as to whether there are crypto-Jews living in the area today, but I do want to emphasize this article. It's a good one that give both sides of the issue.
The story discusses genetics and disease, as well as the possibility that descendants of crypto-Jews still do Jewish rituals today.
