Hello rosie and rolnora,
Thank you both for your information -I have FindMyPast but could not find that entry!
I am wondering now if John was perhaps married two or three times to an Elizabeth ? It does say widower in 1809 and there is a 22 year gap between the age of Elizabeth in 1841 and 1851.
This just seems to get more mysterious all the time...
I appreciate your assistance very much.
Kind regards from Joan
