This former model and showgirl was the wife of Frank Sinatra from 1976 until his death in 1998.
Barbara Blakeley was born in Bosworth, Missouri in 1926 to Charles W. Blakeley and the former Irene Prunty Toppass (died 1993, California); she was raised in Wichita, Kansas.
In the early 1970s, she started seeing Frank Sinatra, as a friend at first and later as a lover. The two were married from July 11, 1976 until his death on May 14, 1998. It was Sinatra’s fourth and final marriage, and the longest-lasting one, despite Barbara’s cool relations with the children from his first marriage. She converted to Roman Catholicism at Sinatra’s request.
