hmm yes its hard when things don't add up or you cannot find documents ,but keep going something will turn up
I do know Wells surname can be found as Wills Welles sometimes
Yes I did look in Cornwall records no Henry found there so if he was born there not bapt there for sure, but don't discount he might have been in Cornwall my own family
Wells although from Dorset were in Cornwall 1851 that being Ganey* Jane * Wells with husband Thomas Jefferies, you never know could a link ?
As you know when any census was taken they did not always write correct info it was dependant of who told them and how it sounded and birth dates vary so much
so its possible Ann could be Keziah maybe she preferred that name or who ever did census could not spell its a possiblitlity
Would be interesting to know about the Frome marriage though could it be them I wonder?
Just realise if you think Henry is child of George Wells & Elizabeth Smith that is part of my family line , will check my notes see if I can figure anything
