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]
When Barr was three, she got Bell's palsy on the left side of her face. She said, "[so] my mother called in a rabbi to pray for me, but nothing happened. Then my mother got a Mormon preacher, he prayed, and I was miraculously cured". Years later, she learned that Bell's palsy was usually temporary and that the Mormon elder came "exactly at the right time".[9]
Barr has stated that she is on the autism spectrum.[12] At six years old, she discovered her first public stage by lecturing at LDS churches around Utah and was elected president of a Mormon youth group.[9]
At age 16, Barr was hit by a car, and the car's hood ornament impaled her skull; the incident left her with a traumatic brain injury.[9] Her behavior changed so radically that she was institutionalized for eight months at Utah State Hospital.[13][14]
In 1970, when Barr was 18, she moved out by informing her parents that she was going to visit a friend in Colorado for two weeks, and never returned.[13]
The following year, Barr had a baby, whom she put up for adoption. They reunited amicably 17 years later.[15]
