Well, to make a long story short, Fran Drescher is Jewish!
Since Fran Drescher'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 Jewish too.
Fran Drescher (whose full birth name is Francine Joy Drescher) was born on September 30, 1957 in Kew Gardens, Queens, New York, U.S..
She is best known for her role as Fran Fine in the hit TV series The Nanny, and for her nasal voice and thick New York accent.
