Nancy Sinatra Sr., first wife of Frank Sinatra

LOS ANGELES (AP) — Nancy Sinatra Sr., the childhood sweetheart of Frank Sinatra who became the first of his four wives and the mother of his three children, has died. She was 101.

Her daughter, Nancy Sinatra Jr., tweeted that her mother died Friday and a posting on her web page said she died at 6:02 p.m. but didn’t indicate where she died.

“She was a blessing and the light of my life,” her daughter said.

Attempts to reach representatives for Sinatra Jr. late Friday were unsuccessful.

Nancy and Frank Sinatra had been dating as teenagers and married in Jersey City, New Jersey, on Feb. 4, 1939, just as Frank’s singing career was about to take off. Three years before marrying the former Nancy Barbato, he had landed a 15-minute radio show on local station WAAT.

During the marriage’s early years, the Sinatras lived in a modest apartment in Jersey City, where their two eldest children were born. For a time she was employed as a secretary while her husband worked as a singing waiter.

After Sinatra became a pop-music sensation in the 1940s, the couple moved to Los Angeles, where the singer would also become a movie star and notorious womanizer.

Nancy Sinatra left Frank after his affair with actress Ava Gardner became public knowledge. Weeks after the pair’s divorce became final in 1951, Sinatra’s ex-husband married Gardner, while Sinatra went on to raise the couple’s three children: Nancy, Frank Jr. and Tina.

After the gossip over the divorce and Gardner marriage died down, Nancy Sinatra devoted herself to family and numerous celebrity friends, largely withdrawing from the spotlight. She not only outlived her husband, who died in 1998, but her son, who died in 2016.

She is credited, under the name Nancy Barbato, on the Internet Movie Database with just two TV and film appearances, in her daughter Nancy’s 1975 concert film, “Nancy and Lee in Las Vegas.”

In later years she would become known as Nancy Sr., especially after daughter Nancy became a 1960s singing star in her own right with “These Boots Are Made For Walking” and other hit songs.
