Crough was 7 when The Partridge Family premiered, and the strawberry blonde stayed through the entire four-season run of the show, which starred Shirley Jones as the widowed mother of a family of pop musicians. (Tracy, the youngest of the five kids, played percussion instruments like the tambourine.)
Crough later had a regular role on the NBC comedy Mulligan’s Stew, which aired for just a handful of episodes in 1977. Her last onscreen appearance came on a 1980 NBC telefilm, Children of Divorce.
Crough grew up in Los Angeles as the youngest of eight children. In 2010, she appeared on the Today show and said she was working as a manager at an Office Max in Arizona.
