William Charles Lade
I have Ancestry found the following:
British Army WWI Pension Records 1914-1920 for William Charles Lade
However, I cannot find any Life Story for him on this site.

Reading his documents he seems to have been home service only which is why he wasn't initially included, I've set a lifestory up for him here https://livesofthefirstworldwar.org/LifeStory/7665940
