Matthew Jewell was the third child of Absolam Jewell and Catherine Davies, and was baptised on the 25th March 1754, in the Parish of Wendron.
Unfortunately there is no record of Matthew marrying in Wendron, however there is a record of a Matthew marrying Sarah Teague in Probus on 11th June 1782, and another Matthew married Grace Asher also in Probus on 1st October 1788. Once again further research is required to determine if any of these Matthews is "my" Matthew. I should also mention that the Parish of Probus, is not near the Parish of Wendron, so it is highly unlikely.
If anyone has anymore information about Matthew, or you feel you may be one of his descendants, please contact me at firstname.lastname@example.org
