I am Bonnie Franklin's sister and we are the granddaughters of Leo Birnbaum a.k.a. Leo Burns of the vaudeville dance team "Burns and Foran." We are trying to find out any information we can on our grandfather, including information about "Burns and Foran." If you have information, we would be extremely grateful to communicate with you about it. Our father, Leo's son, is 90 years old now and we are racing against time trying to help him fill in the gaps of his father's life and career. Thanks so much!
