Jones’s family was one of the more prominent of the proverbially poor gentry of Radnorshire, with an estate concentrated in the parishes of Llanfihangel Nant Melan, Old Radnor and Gladestry in the centre of the county. The Member’s father, Griffith, was the first to adopt a settled surname rather than the Welsh patronymic, and served as sheriff in 1563-4.
It is unclear when Jones entered his patrimony, but his participation in Radnorshire’s small political elite was assured by his marriage, probably before he reached 20, to a daughter of John Price of Pilleth. The couple produced an heir, Richard, to whom Jones conveyed the majority of his property, estimated at £80 p.a., via a marriage settlement of March 1610.
The Price association allowed Jones’s star to rise within county politics, and to attain the position of deputy lieutenant by 1623. Seen as a trusted associate by the Pilleth Prices, the latter probably facilitated his entry to Parliament as county Member in 1628, a seat held between 1624 and by his brother-in-law, James Price II. However, he appears to have made no impact in the House, as the ‘Mr. Jones’ indiscriminately recorded in the Journal was almost certainly the lawyer Charles, Member for Beaumaris. As one of the Welsh knights, Jones was nevertheless eligible to attend bill committees concerning the estate of William Morgan of Penrose, Monmouthshire and the sale of lands belonging to John Fleming (15 Apr. 1628; 23 Feb. 1629).
Jones acquiesced in the financial innovations of the 1620s and 1630s, his Forced Loan payment being only £3, possibly because he had earlier lent £10 on Privy Seals.
Jones lived quietly at Trewern during the 1650s, but was involved in litigation in 1658 over the estate of his brother-in-law, Charles Price*, who had made him an executor of his will.
