PHOENIX (AP) – 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.

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. Christine and Phyllis, 86 and 81 respectively, live in Las Vegas.
