Hello,
I am hoping someone maybe able to help with a lookup or advice. I am looking for my great-grandfather: John Alexander Nicholls. All I know is that he fought in WW1, wasn't killed in action but died later of illnesses resulting from being gassed in the war (conjecture from my grandmother). I have no idea what regiment, although he was an electrician so possibly the Royal Engineers. I know this is a long shot.
Thanks
