Sarah Palin deals extensively with her Irish Catholic roots in her new autobiography "Going Rogue."

Her mother Sally Ann Sheeran was “born into a large educated Irish Catholic family in Utah,” she reveals in her book. She was descended from Roscommon immigrants.

Her grandfather, Clement Sheeran, was a mediator for General Electric and “was wild about Notre Dame,” she remembers

“Grandpa was witty and poetic,” Palin remembers, “like a graying Ronald Reagan. He loved to entertain us with silly poems and Irish songs and sayings.”

At Catholic school she remembers arguing with nuns over catechism and a particular nun who tried to teach her to write the letter E which she had difficulty with.

Her mother made the switch from Irish Catholicism after a friend urged her to attend a new evangelical church in Anchorage. “There Mom found a depth of spirituality she had been seeking,” Palin writes.

Not long after Palin began attending Sunday school at an Assembly of God church She attended a youth Bible camp in Alaska and "I made the conscious decision that summer to put my life in my Creator’s hands."

Her siblings and her left the Catholic faith and were baptized together in a freezing Alaska lake by Pastor Paul Riley.
