William "Stumpy" Zevon was the father of Warren Zevon and the grandfather of Jordan and Ariel Zevon. He was born as William Zivotovsky, and was related to folk/blues singer Jedaiah Zivotovsky. He worked as a boxer (serving as part of the inspiration for Warren's "Boom Boom Mancini" song), but was also a small time criminal, an associate of Mickey Cohen (again, probably part of the inspiration for his son's gritty outlaw songwriting). He was of Russian Jewish origin and lived in Chicago, Illinois. He was married to Beverly Cope Simmons, Warren's mother. The family moved to Los Angeles, California after Warren was born and William and Beverly divorced when he was 16. Warren Zevon's middle name was "William".
