He was a younger son of Oliver Jones (d 1685) of Fonmon Castle, Glamorgan, Wales, and his wife Mary Button.
Robert was educated at Jesus College, Oxford, matriculating at 15 in 1698.
He was appointed High Sheriff of Glamorgan for 1703-1704, replacing his father-in-law Sir Humphrey Edwin. In 1712, when Sir Thomas Mansel was ennobled as Baron Mansel, Jones was returned to Parliament for Glamorganshire in the Mansel interest at a by-election on 13 January. He was a High Tory, while Mansel was a more moderate Court Tory, but Mansel may have felt obliged to make a concession to the local High Tory interests to prevent their attachment to the Duke of Beaufort"s interest.
He was again returned for Glamorgan at the 1715 election, and was noted as a Jacobite, keeping a portrait of the Pretender.
However, he did not long survive the Whig reascendancy, dying in December 1715 at the age of 33.
