Jewish Destiny in a Cheek Swab

Recently, junior congresswoman Alexandra Ocasio-Cortez invoked distant Jewish roots at a Queens synagogue as a preamble to celebrating the mash-up of Puerto Rican culture and by extension all cultures: “I think what it goes to show is that so many of our destinies are tied beyond our understanding.” Last year, a minor fuss erupted after New York State Senate candidate Julia Salazar made dubious claims to Jewish ancestry.

Such claims, some more credible than others, have been made by various politicians and public figures. Indeed, possible Jewish ancestry has fascinated both Jews and non-Jews when it comes to American historical figures, reaching as far back as Alexander Hamilton (not to speak of my fellow columnist Stuart Schoffman’s fascinating piece on Lincoln). A recent study suggests that one in four Latin Americans has some Jewish ancestry, most likely a vestige of Jewish conversos fleeing the Inquisition to settle in the New World.

There’s something tantalizing about the prospect of uncovering your past with a cheek swab. DNA evidence is refreshingly precise in contrast with the hazy knowledge afforded by family legends and hearsay. Thanks to popular DNA analysis platforms like 23andMe, one can uncover deep connections to hundreds of individuals, of the past and present, whom you have never met. Putting aside the genuinely amazing stories of immediate family reunions that have emerged from 23andMe, the phenomenon also speaks to those with more distant threads to unravel. In one promotional video on 23andMe’s website a Lebanese American man who always wondered about his mother’s gray eyes and his love for Martin Scorsese movies is astounded to learn that he is 9 percent Italian. In that same report he finds some Ashkenazi Jewish heritage as well, a discovery he suggests might hold some promise for peace in the Middle East.

I recently purchased my own 23andMe DNA kit in a Black Friday sale and mailed it in just as Ocasio-Cortez released her Jewish heritage announcement. While I don’t struggle with any glaring mysteries about my past, the thought that these results might offer some new knowledge about myself kindled my excitement. But what kind of knowledge, really? And why the excitement?
