Hello my Dad was adopted and I recently aquired a copy of his original birth certificate, which gives the name of his mother but the fathers name is blank. I am told his mother was living with a man when he was born, however they were not married until a year later.
What does this mean? Is it that the father was simply not known or was it common at this time (50's) for the father not to be put on the marriage certificate if the child was born out of wedlock?

Thanks, Toby.
