I found out a few years ago after my dad died (from my mum) that he never knew his bilogical father. I wasn't aware that my grandad was his stepdad. Apparently he found out when he was 18 and was very upset about it. My mum said he carried his photo in his wallet, but she thought she'd thrown it away after he died! She passed away last October and when I was going through her things I found some really old photos. I know some were my dad's as he'd shown me when I was younger. One postcard photo stood out (attached) and he looks spookily like my dad and I'm wondering if he's his father - I have no way of knowing! I've done a DNA test and found some relatives on my mums side, but having no luck with my dad's other than a couple that I can't see a link to. I put the photo into Chat GPT - front and back and what it came back with sounds pretty logical - date/place. It deciphered the scribbled out writing on the back as 'Ernest (Howe/House) Returned with bag, which makes me think he died in the war? Does anyone have any tips on how to find out anymore info? Sorry for the ramble!
