Well, to make a long story short, Rosanna Arquette is Jewish!
Since Rosanna Arquette's mother is Jewish, and in Orthodox Judaism and Conservative Judaism, those with a Jewish mother (or those who underwent a halakhic conversion) are considered Jewish, then that makes her Jewish. Her father is not Jewish.
Rosanna Arquette (whose full birth name is Rosanna Lisa Arquette) was born on August 10, 1959 in New York City, New York.
She is best known for her role opposite Madonna in the 1985 hit film Desperately Seeking Susan. She also acted in other films, such as Silverado (1985) and The Big Blue (1988).
