Priscilla,
Thanks a bunch.
I did check the IGI but must have missed this one. I'll do more research and see if this is possibly my Grace Hancock.
On the 1861 census she lists her birthplace as Tawstock and her husband lists his as King's Nympton which from the Devon map I have shows Yarnscombe as half way between their birthplaces.
However, the date is certainly within the possible so I'll hang onto the info as I continue searching.
Thank you again for your help,
Barbara Tracey
