Reader, I married him in Kentish Town (9)

I believe the answer is:
rochester
'kentish town' is the definition.
(Rochester is a town in Kent)
'reader i married him' is the wordplay.
I cannot quite understand how this works, but
'him' could be 'rocheste' and 'rocheste' is found within the answer.
A single letter 'r' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for rochester that I've seen before include "Jane's husband eventually" , "Earl of ---, C 17 poet" , "One city" , "Man Jane married" , "Novel hero" .)
