This is the weirdest part of her doing the blood libel thing, although maybe it’s because of the whole Mormon thing? I don’t know.

Barr was born in Salt Lake City, Utah to a Jewish family. She is the oldest of four children born to Helen (née Davis), a bookkeeper and cashier, and Jerome Hershel “Jerry” Barr,[8] a salesman.[9] Her father’s family were Jewish emigrants from the Russian Empire, and her maternal grandparents were Jewish emigrants from Austria-Hungary and Lithuania.[8] Her paternal grandfather changed his surname from “Borisofsky” to “Barr” upon entering the United States.[9] Barr’s great-grandparents were murdered during the Holocaust.[10]

Her Jewish upbringing was influenced by her devoutly Orthodox Jewish maternal grandmother.[9] Barr’s parents kept their Jewish heritage secret from their neighbors and were partially involved in the Church of Jesus Christ of Latter-day Saints.[9] Barr has stated, “Friday, Saturday, and Sunday morning I was a Jew; Sunday afternoon, Tuesday afternoon, and Wednesday afternoon we were Mormons.”[11]
