He married three times. On December 5, 1949, he married his high-school sweetheart, Naomi Shackleford. The couple had two children, Debbie (b. 1954) and Mark Lee (b. 1955), before divorcing in 1961. Hazlewood used Naomi's maiden name for The Shacklefords, a short-lived vocal group he formed with Marty Cooper in early-1960s Los Angeles; Naomi herself contributed vocals to the group's recordings. In 1983, Hazlewood married Tracy Stewart, whose daughter Samantha (b. 1980) he raised as his own; that marriage also ended in divorce, in 1992. In November 2006, less than a year before his death, he married Jeane Kelly, his girlfriend since 1993, in a Las Vegas drive-through ceremony.
