Maggie Gyllenhaal just found out what her real birth name is

Maggie Gyllenhaal’s name seems to fit her, and she’s used it on all of her official documents all her life. However, her birth certificate does not say “Margaret” like everyone, including Maggie thought, it would.

When her parents dug up her birth certificate so she could legally take her husband Peter Sarsgaard’s last name, everyone was shocked. “My parents couldn’t find (my birth certificate),” she told Live! With Kelly and Michael. “Finally they pulled it together and got it for me and it says my name is Margolit, which I really love, but it’s not my name. I grew up Maggie, Maggie’s on everything…

Even her parents were in shock. “(My parents) didn’t remember (that they named me Margolit) and in fact they still insist that my name is not Margolit,” she says.

Maggie’s currently staring in a Sundance TV mini series call An Honourable Woman that’s getting great reviews.
