You Won't Believe Your Eyes
The Ross Sisters were a trio of female sibling singing dancers consisting of Aggie Ross, Elmira Ross, and Maggie Ross.
Their real names were Veda Victoria, Dixie Jewel and Betsy Ann Ross). The Ross Sisters performed as a 3-part harmony trio, in which they also danced and did acrobatics and contortionism. Their public attention peaked during the 1940s, during which they were featured prominently in the film Broadway Rhythm. A shortened version of this same clip also appears in the compilation film "That's Entertainment! III" (1994).
Published sources and some official records conflict on the names and dates of the sisters, as they apparently used each other's names at different times. When Broadway Rhythm was filmed, birth records indicate that the sisters were between about 14 and 17 years old. It has been suggested that in order to perform in London in 1946, the two younger sisters assumed the identity of their next oldest sister to make them appear to be older than their true age. The oldest of the three used the identity of an older sister who had died as an infant. They were recorded on the Queen Mary passenger list as Dorothy (aged 21), Eva (20) and Victoria (18), though their real names and ages were Betsy Ann (20), Veda Victoria (18), and Dixie (17). Each sister also used a different stage name.
