Background
Theophilus Jones was the son of Hugh Jones (d 1799), vicar of Llangammarch and then Llywel, Brecknockshire, and a prebendary of the collegiate church of Brecon. And his wife, Elinor (d 1786), daughter of the historian Theophilus Evans. The death of his father gave him an additional degree of financial security, and following his appointment as deputy-registrar of the archdeaconry of Brecon, he sold his business in 1808 to have time to write.
