St. Jacques was a lifelong bachelor. In August 1969, St. Jacques granted an interview to columnist
Earl Wilson and told Wilson of his plans to adopt two African-American boys who were six and seven years old. By the early 1970s, St. Jacques said he had two older sons, Raymond, Jr and
Sterling, the latter being adopted. In a 1973 interview, St. Jacques said that Raymond, Jr was living in
Boston. Sterling appeared in St. Jacques's 1973 film
Book of Numbers. He also worked as a dancer and as a frequent figure in New York City nightclubs and society life. In her 2016 memoir
Walking with Muses, Cleveland said that their engagement ended because Sterling was gay. According to Cleveland's memoir, Sterling St Jacques died of complications of
AIDS in 1992. (His death has never been officially confirmed.) In a 1988 interview with the
Chicago Tribune, St. Jacques still said he had two sons and that Sterling was appearing on a television show in
Düsseldorf. ==Activism==
