Looking for Piercey Family

I was born in Toronto in 1967. My mom's maiden name was Piercey. She was 19 yrs old and my dad was 20 yrs old in 1967 and both were from Nova Scotia. My adoption took place in 1970. I know they went back to Nova Scotia after the adoption took place, but I don't know where. My mom had 2 half sisters and my dad was the eldest of 12. My birth name was Brian Gerald Piercey. I just want to let them know I turned out great.
