He seems like a front runner at the moment - he has the right occupation, the name is close, there doesn't seem to be a death for him in England/Wales at least, and a change of name/age isn't unusual especially if he was avoiding his first wife!
A bit mysterious where he was in 1901/1911 in that case - Europe?
It does appear the details from marriage are going to be necessary to untangle what happened, though.
