Is Melissa Gilbert Jewish?

Is Melissa Ellen Gilbert Jewish? I'm asking about the American actress and writer. She is best known as a child actress who co-starred as Charles Ingalls's second daughter, Laura Ingalls, on the TV series Little House on the Prairie.
What is her religion, is she Jewish?

Yes she is Jewish. She once said it on a newspaper interview.

Although she was raised Jewish, she didn't have any formal religious education or training.

That's why when people ask her about her religion, she says she's 'Jewish,' emphasizing the 'ish' at the end.
