Dorothy McGuire Williamson, the middle sister of the 50s famed singing trio The McGuire Sisters, passed away at the age of 84. The singer, who was well known for her identical look with her two sisters, died of natural causes in Arizona.
Dorothy's daughter-in-law Karen Williamson told The Associated Press that the singer died at her son Rex's home in the Phoenix suburb area of Paradise Valley. Before her death, she reportedly suffered Parkinson's disease and age-related dementia.
Dorothy started singing with her sisters Christine and Phyllis since they were kids. The siblings performed in churches and weddings before getting their big break on Arthur Godfrey's Talent Scouts show in 1952.
They got at least six Gold records including 1954's "Sincerely" and 1957's "Sugartime" during their career spanning more then a decade. They performed in a number of events including one attended by Queen Elizabeth II of Great Britain.
They were inducted into the National Broadcasting Hall of Fame in 1994, the Vocal Group Hall of Fame in 2001, and Hit Parade Hall of Fame in 2009. They last performed together as a group in the mid-2000s. Her sisters Christine, 86, and Phyllis, 81, now live in Las Vegas.
In addition to her sisters, Dorothy is survived by her husband of 53 years, Lowell Williamson, two sons, two step-children and nine grandchildren. A memorial service is scheduled for September 15 at Valley Presbyterian Church in Paradise Valley.
