Their father, William Herbert Lennon (1915–1969), worked as a milkman for many years before getting a job at a local golf course. Their youngest sister, Mary Frances, died in infancy in 1954 after being struck by a speeding car. The Lennon Sisters were born into a family of twelve children (seven sisters and five brothers), all born in Los Angeles, California. In 2001, they were inducted into the Vocal Group Hall of Fame. They continue to tour around the country and, until recently, performed annually with their Christmas show at The Andy Williams Moon River Theatre in Branson, Missouri. The current line-up of the Lennon Sisters is a trio consisting of Kathy, Janet, and Mimi. In 1999, younger sister Mimi (born Miriam Theresa, October 16, 1955) replaced Peggy upon the latter's retirement. After the show was cancelled, they partnered with Andy Williams to create a successful Las Vegas residency, which lasted a decade.

From 1955 to 1968, the group appeared regularly on The Lawrence Welk Show (receiving union scale wages) before having their own television variety show, called Jimmy Durante Presents the Lennon Sisters, with Jimmy Durante. The quartet originally consisted of Dianne (aka DeeDee born Dianne Barbara, December 1, 1939), Peggy (born Margaret Anne, April 8, 1941), Kathy (born Kathleen Mary, August 2, 1943), and Janet (born Janet Elizabeth, June 15, 1946). The Lennon Sisters are an American vocal group that has been made up, at one time or another, of three or four sisters.
