Oh Boy Julie!
Have you got a problem!!

In 20+ years of researching I have come across several similar cases to this in both World Wars and never managed to solve any of them!

Even if you could narrow down which units were stationed nearby 9 months before his birth, you would probably have several hundred candidates for granddad.

If his father's name is not on his birth certificate, his mother probably took her secret to the grave.
Good luck!!
Regards, Bill
