I wanted to answer your message but no email address so trying this way. The Charles Corney you are trying to find is part of the Corney family I am researching in Australia. I lost track of him along the line I do know of two children one of which came to Australia and I believe he too was a Mariner. The family settled in Queensland, Australia and I have all of that tree done. I wondered if Charles may have died early as I couldn't pick either Charles or Elizabeth up in the Census; do you have any idea what happened to them??
Thanks for the marriage place didn't know that; they had the two children in a place called Chevenning (I think it's spelt) in Kent.
