Thank you for your reply.
Since Jemima Caton was born about 1792, she died prior to the death certificates which are on the Missouri Death Records site for the years 1910-1961. Her alledged so, Thomas D Cayton, his death certificate is found on that site.
I have found nothing on Find A Grave.
I have looked on the Boonve CO MO Cemetery Project site, that site seems to have been active between the years 1999 and 2002. None of the links on that site are working.
There are no listings for her on the USGenWeb archives.
Other than census records (last census Jemima Caton is found in is the 1860 census for Perche, Boone CO, MO), there is no information on her on the FamilySearch site.
I've hit that proverbial 'brick wall' with Jemima Caton!
