I met a girl in 1973-4 in Ft. Gordon Ga... she was enlisted and we were pregnant but lost touch... >email address removed per site rules<

This is not enough to get get started with ? Do you do her name, have any information such as social security ?

Were you there when child was born ? Do you know child's name ? Girl or boy ?

At this point assuming you know her full name, you hire a private investigator to locate her

I have none of that information, however the lady I was with was young and myself. I hope by the vagueness that I will find her, and my born child.
I do not have the finances to use an investigator or I would go that route, thank you for your thoughts.
