What religion is Emma Stone?

Answer 1

Well, based on her history and her attendance at Xavier Prep, a Catholic all girl school, we can infer that she is Catholic. But then again she said in a recent interview that the mother side of her family has some "unusual secret practices" such as gravestone touching. So it's hard to say but safe to infer that she is Catholic.

Answer 2

She's Swedish. Her father is Swedish and her mother is from the east coast. It's rumored that she has Dutch Pennsylvanian heritage.
