My GGF disappeared from my DGF's life before he was a year old.
My DGF was born in the First World War. His parents got married, unwillingly I suspect, a few months after he was born. I have their marriage certificate. I doubt they were having any sort of grand romance. GGF returned to the Western Front and was never heard from again.
It was my GF's life long shame that he was born illegitimate and raised by his mother and had his mother's last name. There is nothing written on his birth certificate where his father's name should be.
However, he assumed his fathers last name and was always known by it. My DGP's marriage certificate records his father as, 'missing presumed deceased.' This was the 1940's.
However, he got lodgings in a hostel practically at the bottom of the road where wife and son lived. Did he attempt to visit them ? Who knows ?
When GGM died in the 1960's, her death cert records her as: widow of Joe Bloggs, soldier, presumed deceased.
I have done some family history research as I've always wondered where and when GGF died. Suffice to say he was a rogue, who, among other crimes, married bigamously in 1942. The year after his own son was married.
I am closing in, I believe on when and where he died. I am within ten years of finding out, I hope. His second wife married again. As a widow ? I don't know. I will use research tools to get her marriage cert. Just like I got GGF's second marriage cert, on which he is recorded as a bachelor !
