Hi HL
Thank you very much for all of your help with this. Not having an age for Jane makes the search very difficult so I appreciate you searching other areas

.
The only Janes I could find were a Jane Collins bap 8 July 1750 in Chatham Kent by John and Elizabeth Collins and on Family Search, a Jane Collins bap 4 July 1731 in Bethersden Kent by George and Jane Collins. But not knowing an age for Jane it's hard to know if either of these are right

. And not knowing the area makes it hard to know if these places are close enough to Rolvenden to be even included in a search.
I also tried to check Settlement Certificates for the area/name/years but no luck with these either. The information on Ancestry re the marriage of William and Jane that lists William as a widower, identifies Jane as a spinster both OTP.
As William is identified as an Innkeeper at his marriage perhaps I can try for his will/probate records as these may turn up some information. Do you have a record of his death date?
Again thanks very much for all of the searching for the origins of the elusive Jane
regards
Barbra
