Was your Bmom DOB,Feb 28,1913?

Hi, I am looking for any 1/2 brothers or sisters. My mother was born: Beatrice Florence Lillian Freebody DOB: Feb 28,1913 in Wainwright,AB I was born Sept 26,1944 and raised by the father and his parents in Edmonton. She did marry my father ( Ault) in Nov23,1944 in Sask. He said they didn't divorce. My mother abandoned us when I was 6 months old so she could have taken up with another man and may have used his surname. I was told by my father that she died in Vancouver.Guessing about 1960 but not sure. She may have been buried using another persons last name. I was just wondering if there is any siblings from my mother, and would like a friendship only? You can contact me at: grossum@shaw.ca
