Thomas Evans (known as Tomos Glyn Cothi) was born in 1766 at the farm Capel St Silyn in Gwernogle, Carmarthenshire.
On the 1841 Census, Capel St Silyn was occupied by Evan Evans, who was born about 1821.
Later still, the farm was occupied by John Evans, who was born about 1822 and lived at Capel St Silyn from about 1864 until his death in 1893.
Obviously all three men have the same surname, and it was common for farms to be inherited or otherwise passed on to other members of a family.
Thomas and John were both congregationalists (Thomas later became a unitarian), and as there is no matching baptism record for Evan, it seems reasonable to believe that he was also a non-conformist.
All of these factors taken together imply a decent possibility of a family connection between at least some of them, but I can't find anything as of yet. Does anyone have any suggestions of how we might be able to try to connect them please?
