Thank you for your efforts Trish.
The parents were ,John Jones b Clyro 1777, Ann b Hereford town according to the ,Dowlais Merthyr 1851 Census but haven`t been able to find them on the 1841 anywhere. John describes himself as a journeyman baker ,children I have found so far,Mary Ann b Chepstow c 1818,Catherine b Leigh GLS 1821 and Louisa b 1830 Brecon town. I`m sure there are more children somewhere given the gap between Catherine and Louisa.
Also given the Clyro connection they are very likely to have lived in Hay at some time I would have thought which wouldn`t then eliminate Thomas as their son.
John Jones is on the 1861 living in Dowlais with daughter Catherine Nancarrow widow of Walter Chambers (b Glasbury)re -married 1858.Two of Catherine`s children go and live with the Michael`s in Hay after Walter`s death.
That`s why I can`t understand a "stranger" from Talgarth registering James Michael`s death.
