PHOENIX — Dorothy McGuire Williamson, who teamed with sisters Christine and Phyllis for a string of hits in the 50s and 60s as the popular McGuire Sisters singing group, has died. She was 84.
Mrs. Williamson died Friday at her son’s home in the Phoenix suburb of Paradise Valley, daughter-in-law Karen Williamson said. She had Parkinson’s disease and age-related dementia.
The McGuire Sisters earned six gold records for hits including 1954’s “Sincerely” and 1957’s “Sugartime.” The sisters were known for their sweet harmonies and identical outfits and hairdos.
They began singing together as children at their mother’s Ohio church and then performed at weddings and church revivals. They got their big break on Arthur Godfrey’s Talent Scouts show in 1952 where they continued to perform for seven years.
Mrs. Williamson was married for 53 years to Lowell Williamson, a wealthy oilman. The couple had two sons, Rex and David. AP
