Interesting posts. Thanks guys.
Best thing I learned is half of the Enterprise bridge crew is Russian Jewish in origin, even the alien
Brent Spiner too, and all the Ferengi on DS9 (Shimmerman, Grodencik, Eisenberg, and Shawn). Not necessarily Russian, but they're all Ashkenazic Jews.
Ashkenazic is more appropriate than Russian, especially considering (if I remember well) since Ashkenazic originally designated Jews of Germany and Sepharadic Jews from (Muslim) Spain. Shatner's grand-parents from his father side were Austrians and Nimoy's parents were Ukrainian. Anyway, the vast majority of North-American Jews are Ashkenazic.
