In page Bobby Darin:

"

Darin's maternal grandmother, Vivian "Polly" Fern Walden, (born in 1891) was of English, Danish and Norwegian ancestry[3][4][5] and had been a vaudeville singer before Darin's birth.[6] His maternal grandfather, Saverio Antonio "Big Sam Curly" Cassotto (born January 26, 1882), was of Italian descent. He had been a made man and "soldier" in the Genovese Crime Family as well as a close associate of Frank Costello. Sam served as a witness at Costello's 1914 wedding, though the relationship soured after he accused Costello of withholding money that was meant for Cassotto's family.[citation needed] Sam Cassotto died from pneumonia in 1935 while in prison, a year before Darin's birth.
