Find Ancestors

I was born 23 03 1963 My name's Sharon Thomson My mother's maiden name was Annmarie Thomson. I'm trying to find my father. My mother told me she met him while he was lodging at my grans house her mothers this was way back in 1962 or so Glasgow Scotland. She told me that he was studying accountancy at Strathclyde UNI then. Things weren't meant to be between my mother and father then. My dad married to a lady called kate but he did know of me I'm told . It's taken some time but finnally Mums come up with a surname she thinks may be his I'ts the only thing thats made the search so hard. So if your out there Norbert Ojukun please contact your first born cause I would really like to meet you.
