My father’s mother died when he was 4. He lived with his father and his mother’s mother in her (the grandmother’s) house. During my father’s childhood (1930’s) his grandmother brought a girl home to live with them. I don’t think my father knew quite who she was.
A lot later there was a boy at my junior school who was this mystery girl’s son. My sister remembers him (he was a bit of a bully until told of the family connection
). Looking on freebmd, I found him and his mother’s surname is the same as the married name of the one surviving sister of my dad’s mother. I also found his mother’s marriage at just the right date. However, I can’t find a perfect match for his mother’s birth. Her forenames were Jean M. The only Jean M. was born in 1937 and the mother’s maiden name doesn’t match. Moreover, my Dad was then 13 and I don’t think that matches: by the time someone born then was the age she seems to have been when she arrived in the household, he had left for the war. Moreover, she would have been too young to marry in 1951.
There is however, a Jean F., born in London (so well away from the place where my Dad’s family were), who was born in 1929, so closer in age to my Dad, and the mother’s name and maiden name are the same, and the same as the married name of my grandmother’s sister.
It seems that the mystery girl was therefore probably the illegitimate daughter of this aunt, but should I be worried about the exact correspondance in the birth reg?
