The wills of the 2 John Bartons who died in the 1870s were no use. One was a very simple will, leaving everything to his wife Elizabeth, with no details of family or property.
The other was extremely long, but confirmed that this John B was childless - he left everything to his brother's (William) children. (his nephew was another John Barton).

So, I still can't get the Bartons back to 'Tonbridge'.
Do you have access to Hythe Dymchurch and Hawkinge PR's? They are not online or on CD as far as I can ascertain, and I'd like to see if John Barton appears in this area before his marriage to Ann.
