Mo

Ringo was married to Maureen Starkey "Mo" Tigrett in 1965 and divorced in 1975. The couple had three children, Zak, Jason and Lee. Like Ringo, Maureen was born (as Mary Cox) in Liverpool. She left school at 16 and changed her name to Maureen when she began her career as a trainee hairdresser in Liverpool.

She met Ringo when he was performing at the Cavern Club. In January 1965, Ringo proposed at the Ad Lib Club in London and the couple was married February 11, 1965. Their first child, Zak Starkey, was born on September 13, 1965.
Maureen sang backup vocals on "The Continuing Story of Bungalow Bill" and was, along with Yoko Ono, in attendance at the rooftop concert in 1969 and the very first song in the Beatles' Apple Records catalogue was a special private recording sung by Frank Sinatra as a favor to Ringo as a 22nd birthday gift for Maureen in 1968. Sammy Cahn rewrote Lorenz Hart's lyrics to "The Lady Is a Tramp" and personalised them about Maureen. Sinatra recorded the song in Los Angeles, and only a few copies were pressed before the master tape was destroyed.
By 1975, the marriage had fallen apart and the couple was divorced on July 17 of that year. In 1989, Maureen married Isaac Tigrett, of Hard Rock Cafe and House of Blues fame.
During the opening of the House of Blues, Maureen fainted. What was initially thought to be anemia turned out to be a form of leukemia. She died of complications from treatment for leukemia, aged 48, on December 30, 1994 at the Fred Hutchinson Cancer Research Center in Seattle, Washington. She had recently received bone marrow from her son Zak. Her four children, mother Flo, husband Isaac Tigrett and ex-husband Ringo were all at her bedside when she died.
Paul McCartney wrote the song "Little Willow", in her memory and dedicated it to her children. (Click the link below)
