I'm afraid not. He was born in Wales in 1855 so it's definitely the right period. I know he was in hospital in Baltimore in 1915. His granddaughter thinks he died in Boston years later but she's in her eighties now and no-one in the family talked that much about him, so I'm not sure how reliable her info is. She certainly didn't know about the hospital in Baltimore. I only found out quite by chance as I spotted it in a tiny notebook his son was using during WW1. Nothing next to it - just his name and the name of the hospital. I tried contacting the hospital to see if they had archives and had a crazy conversation with a receptionist who was quoting patient confidentiality to me!! Anyway, I'll keep at it. He deserves it.
