If you look closely to his mother's name on his birth certificate her name ends with ‘Wilson’....why isn't it Cruz? Were Mom and Dad married when Ted was born? or did they get married later on?

This was her previous married name and Mr. Wilson lives in England...England and Canada are under ‘British Rule’ so she wouldn't have to have a passport to travel from England to Canada....

That line reads

NAME OF MOTHER BEFORE MARRIAGE.
