I found some information at the Internet Movie Database:

She had 3 sons with David McCallum (I), one of them adopted. The adopted son died of an accidental drug overdose in 1989.

She had one daughter with Charles Bronson

Diagnosed with breast cancer in 1984, thereupon undergoing a mastectomy.

Both of her husbands, -Charles Bronson and 'David McCallum' , were stars of John Sturges's Great Escape, The (1963).


Personal quotes
"I'm in so many Charles Bronson films because no other actress will work with him."

Whatever place I read about all of the children evidently neglected to parse out who came along when. I remember driving past the town where they lived in Vermont and thinking it sounded like they had a nice life. I hope, all things considered, that it was, and will help their family sort out things now.
