Peter:
Many thanks for your reply.
When I posted above I was going by the name as impressed on his Queen's Sudan Medal. Since then I have found out that his name was PROTHERO, and have acquired copies of his attestation papers and medal entitlement files.
The handwritten document for the medal appears to have an 's' at the end of the name, while the typewritten list shows it spelled correctly.
This is an error that was fairly common in those days, sad to say.
Again, thanks for offering your help.
Martin
