Looking for Birthmom (Twinette Reid)

I was born in Montreal June 19, 1973. Birthmom Twinette (nee Reid) was from Jamaica, and was last known to be living in Toronto. We have been trying to find each other but keep missing each other. My birth name was Sandra Elizabeth or Sandra Marie. Please help if you can...I also have at least one brother that I have never met... Thanks Laura
