Well, the other came back this week with results. But nothing useful.
It basically said that a search was conducted +/- 5 years from the date indicated and they did not find anything.
I think I am over thinking this military thing. Even if the child was BORN on the base, the home address is where I should have requested. I made a request using the location of the military base. That may have been my error.
I know that my father and their mother had an apartment in a nearby city when the second child was just a few months old. I am going to send a request for that city.
Wish me luck, I'm remailing tomorrow!
Back on the grind after some inspiration!
