I'm not sure we're ever going to get a definitive answer on this but Rose Marie's official bio says she was born on August 15, 1923. That would make her 94 years, 4 months and 13 days old today.
However, things she said caused a number of her friends — myself included — to think she might have been two years older than that. That would peg the date of her birth as 1921.
Meanwhile, I just got an e-mail from Rene Thompson, whom I know. She writes…
As a life-long genealogist, I decided to do some digging. I found Rose in the 1925 New York State census living with her mother, Stevaniah aka Stella and her maternal grandparents at 616 E. 17th St. in New York. She was listed as a year old.
So that would be 1924, which would make her 93 today. Her first movie seems to have been the short musical film, Baby Rose Marie the Child Wonder, which debuted on June 12, 1929. Some of the publicity for that film said she was five and some said she was six. So I don't know what to think…
