Simon Jenkins was a witness at the wedding of John Davies (born Tremain about 1826) and Mary Evans (born Penbryn about 1826) at Aberporth Parish Church in 1848. The couple lived at Felinwynt, Tremain 1851-1912.
A christening record at Penbryn 16 July 1820 indicates that a Simon Jenkins was the son of John Jenkins and Mary. John Jenkins, a labourer, was also named as the father of John Davies on the marriage certificate & so I think that John Davies and Simon Jenkins may have been full or half brothers. Simon does not appear on any census records that I can find.
Any further information about Simon Jenkins and his family would be appreciated.
