I can't find them in 1871 so must be out of the country.
In 1861 Charles Calver is single and lodging in Sutton on Hone, Kent. He is in the same house as a Charlotte Davey, the step-daughter of John Paxman (daughter of Ann Paxman from a previous marriage?) Charlotte was born in Upton, Norfolk and so I would think that she bacame Mrs. Calver. You should be able to find the marriage ref on FreeBMD.
Hope this helps, I will look some more when I get a bit more time. Cheers Pam B
