Barbara Marx Sinatra (née Blakeley; March 10, 1927 – July 25, 2017) was an American model and showgirl who was married to Zeppo Marx from 1959 to 1973, and was the fourth and final wife of Frank Sinatra from 1976 until his death in 1998. Barbara Ann Blakeley was born on March 10, 1927, in Bosworth, Missouri, the elder of two daughters of Charles Willis Blakeley (June 29, 1895 – October 5, 1989) and Irene Prunty (nee Toppass) Blakeley (June 22, 1907 – December 15, 1993). At age 10, she moved with her parents and younger sister, Patricia, to Wichita, Kansas, where she was raised and graduated from Wichita North High School in 1946. At age 18, she moved to Long Beach, California. Blakeley married Sinatra on July 11, 1976, and they remained married until his death on May 14, 1998. It was Sinatra’s fourth and final marriage, and the longest-lasting one. She converted to Roman Catholicism before the marriage. According to her book, Lady Blue Eyes: My Life With Frank, “He [Frank] never asked me to change faith for him, but I could tell he was pleased that I’d consider it.” Upon his death, Frank Sinatra left her $3.5 million in assets, along with mansions in Beverly Hills, Malibu, and Palm Springs. She also inherited the rights to Sinatra’s Trilogy recordings, most of his material possessions and control over his name and likeness. The Sinatras founded the Barbara Sinatra Children’s Center in Rancho Mirage, California, in 1986. The center is adjacent to the Betty Ford Center on the campus of the Eisenhower Medical Center. The non-profit facility provides individual and group therapy for young victims of physical, sexual, and emotional abuse. In 1998, a Golden Palm Star on the Palm Springs Walk of Stars was dedicated to her. Barbara Sinatra died on July 25, 2017, in Rancho Mirage, California, of natural causes at the age of 90. She was survived by her son, granddaughter, and two stepdaughters.
