She's related on her father's side of the family to US presidents Washington, Monroe, and Madison. Marlene spent several years living in Osaka, Japan, where her father played baseball in a team for the Japanese leagues. She was living in London, England and working as a model when she was discovered by "Playboy" magazine.
Following her stint as a Playmate Marlene moved to Los Angeles, California and continued to model for "Playboy." She had an uncredited bit part in "My Fair Lady" and a small role as Miss Australia in the lowbrow British soft-core comedy romp "Percy's Progress." Todd Rundgren wrote the song "Marlene" about her. Alas, Morrow's life eventually started to fall apart sometime in the mid or late 70s. She worked for a short spell as a saleswoman in a clothing store in Encino, California. In 2006 photographer Paul Zollo discovered Marlene Morrow living on the streets of Los Angeles as a homeless and destitute woman who calls herself Persephone.
