The DeCastro Sisters were a female trio singing group: originally they consisted of Peggy DeCastro (1921–2004), Cherie DeCastro (1922–2010) and Babette DeCastro (1925–1992). When Babette retired in 1958, a cousin, Olgita DeCastro Marino (1931–2000) replaced her and when Peggy later left the group to go solo, Babette re-joined Cherie and Olgita. Peggy eventually returned and Babette once more retired.
