In reply to your request:
A Henry Jones married a Hannah in Llandybie in 1831, who could be the father
of Henry B Jones, who was born in 1836.
I don't know if you have searched the IGI, because Llandybie, and Llanon have
many baptisms which are recorded, these are the churches and chapels recorded
in the IGI, in both Parishes:
Hendre Calvanistic methodist Chapel 1812-1837
Ebenezer Calvanistic Methodist Chapel 1820-1837
Newhouse Independant Chapel 1734-1837
I hope this is of help to you.
