Recently I found out I have an aunt and uncle (twins) from an affair my grandfather had 50-60 years ago when he was stationed in France. My family is trying to see if they can find them but we have next to god damn nothing for clues, so I guess I'll try to describe the events he told us before he died.

Basically, when he was in his 20s during the vietnam war, he was stationed on an air base near paris. At this time he was recently married to my grandmother, but he met this women and shacked up with her for a couple months, even gave her his wedding band, so thats something to go on. He left and later got a letter saying she was pregnant with twins and I guess he never replied.

So I'm trying to find my Half-american german/Half-french, twin relatives we know next to nothing about. We've tried contacting a newspaper in paris to run an ad of sorts but nothing came from it. If anyone knows of a place or has any ideas on where I might have a small chance of figuring this out, I'd be grateful.

Currently trying to find an old photo of his to help the search.
