Grace Jewell was the first child of John Jewell and Mary Jenkins, and was baptised on the 19th March 1758, in the Parish of Wendron.
A search of the I.G.I, has discovered that Grace Jewell married James Davis on the 16th June 1788. Unfortunately a subsequent search of the Cornwall records, failed to discover any children. It could be that they moved to another County, or migrated overseas. It also possible that they never had any children.
Further research will need to be done to find our what became of Grace and James. If anyone has anymore information about Grace, or you feel you may be one of her descendants, please contact me at firstname.lastname@example.org
