My Great Grandfather Benjamin Williams was in the Welsh Regiment (service number 16624) and also in the Machine Gun Corps (service number 25263).I have his medals as a starting point, but not a great deal more.
Trying to find a Welshman called Williams - Tricky to say the least, especially without a date of birth.
I would love to know which battalion he was in. Also, was the Machine Gun Corps attached to The Welsh Regiment or a seperate unit?
I would suggest you refer to The Long, Long Trail website and perhaps try posting on the Great War Forum, where you will find people more likely to be able to help you than on this forum.
Best Wishes
Gwyn
P.S. My grandfather and great uncle both served in 1 Battalion Welsh Regiment. Their surnames were Evans, which is every bit as bad as Williams!
