kingston or smith falls?

Hi, I want to first say, I'm not adopted. I'm looking for my mother's biological parents. My mother has a mental illness and refuses to sign any papers to let myself have any information on my real grandparents. I know that I have no rights to information threw the C.A.S. because I don't fall into the guidelines. I know the following, my mother was born Jan 23, 1955, unsure where. Adopted in Perth/Smith Falls area. By the Dorman family. I have been told that there's a chance my biological grandmother lives in that area. I'm unsure, if i even have any more siblings. I was born in Kingston, my mother walked out on me at the age 1 and now gives no info. She might have had more children between 1977-present. I was born in 1973 and my half-brother in 1977. I hope to find more anwsers soon. B. Reeves :confused:
