There are some electoral registers, but they are arranged by streets not by people's names.
The ones in question were arranged by surnames. At least those few in the early 1900s that I had time to look at.
Last appearance of William Turner as per 1901 census was the 1902 electoral register
Electoral Polling District Hamsterley
Parish or Township Medomsley
William Turner at 117 Hamsterley Colliery
If anyone wants to attempt to pin him down afterwards they are on findmypast.
