Looking for any help please on my great-great grandparents, Thomas Jones, born approximately 1855 in Llanfihangel Geneu'r Glyn, Cardiganshire, married Mary Evans, born 1853 approximately (although her age changes significantly on census records!) Gwnnws,Cardiganshire. Married approximately 1877? First child Lizzie (Elizabeth) born in 1878 in Tredegar, Monmouthshire, - all the other children were born in Llanfihangel GG. Thomas was a Lead Miner, but became a shepherd and died in Talybont, Cardiganshire in approximately 1938. I did send for a marriage certificate from Aberystwyth 2 Quarter 1877, but I believe this isn't correct. I'm really unsure how to move forward successfully with these names. Any advice would be most welcome.
Mary and Thomas had Lizzie, Sarah, Mary Jane (my great grandmother), John, Harry (Henry) and Thomas.
