From wikipedia..is this the wrong person?
Portman was born Natalie Hershlag (Hebrew: נטלי הרשלג) in Jerusalem, Israel.[1][2] Her father, Avner Hershlag, is an Israeli doctor specializing in fertility and reproduction (reproductive endocrinology).[3][4] Her mother, Shelley Stevens, is an American homemaker who now works as her agent.[3] Portman's maternal ancestors were Jews from Austria and Russia and her paternal ancestors were Jews who immigrated to Israel from Poland and Romania. Her grandfather's parents died in Auschwitz and her Romanian-born great-grandmother was a spy for the British during World War II.[5]
...and yes this is the Natalie Portman you are looking for.
