(CNN) Nancy Sinatra Sr., first wife of legendary singer Frank Sinatra, died Friday at the age of 101, her daughter said.

"My mother passed away peacefully tonight," her daughter, the singer also named Nancy Sinatra, tweeted Friday night.

"She was a blessing and the light of my life. Godspeed, Momma. Thank you for everything."

Her death comes two decades after her husband's, who died of a heart attack in 1998 at the age of 82. "Ol' blue eyes" was one of the most influential singers in the nation, and also appeared in blockbuster films such as "From Here to Eternity" and "The Man With the Golden Arm."
