A reader informs me that Justin Kirk is a member of the tribe.
"His mother is Jewish on both sides of her ancestry," the note read. "This isn't speculation, believe me."
My reader's last name is Kirk. So I'll have to defer to him on this. My apologies to Justin. (If it makes you feel any better, Justin, I honestly think you're a wonderful actor. And don't think I've forgotten how brilliant you were in Angels in America!)
