Dorothy McGuire Williamson, 84, who teamed with sisters Christine and Phyllis for a string of hits in the 50s and 60s as the popular McGuire Sisters singing group, died Friday at her son's home in Paradise Valley, Ariz., said her daughter-in-law, Karen Williamson. 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." They 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 in 1952 on Arthur Godfrey's Talent Scouts show, where they continued to perform for seven years.
