In 1956, Wynter married Celebrity attorney Greg Bautzer; they divorced in 1981. Bautzer and she had one child — Mark Ragan Bautzer, born on 29 January 1960. Wynter, once referred to as Hollywood's "oasis of elegance", divided her time between her homes in California and Glendalough, County Wicklow, Ireland. An antiapartheid advocate, she refused to open a performance centre because she discovered that black and white children would have to attend on alternate days. She also planned to make a film criticising the policy, which was to have been written by an American and filmed in Australia.
