Is it possible to find details of a friend’s father born illegitimately London in 1906? My friend would love to see her father’s birth certificate – both her parents are now deceased. She knows the address where her grandmother was working as a housekeeper when she became pregnant and I know that she went on to settle down with another man after her illegitimate child was born and although she had a daughter with this man and my friends father bore his name she thinks they never married. I have found her grandmother on 1901 census but that is all and I was hoping someone could give me some idea how to continue the search.
