Source-derived summary

John Jones Maesygarnedd (c. 1597 – 17 October 1660) was a Welsh military leader and politician, known as one of the regicides of King Charles I following the English Civil War. A brother-in-law of Oliver Cromwell, Jones was a Parliamentarian and an avid Republican at a time when most of Wales was Royalist, and became one of 57 commissioners that signed the death warrant authorising the execution of Charles I following his trial. After the Restoration of the monarchy, Jones was one of the few excluded from the general amnesty in the Indemnity and Oblivion Act, and was tried, found guilty, then hanged, drawn and quartered at Charing Cross.

Biography

John Jones was born in about 1597, the son of Thomas ab John or Jones and Ellen, daughter of Robert Wynn ap Jevan esq. of Taltreuddyn, at Maes-y-Garnedd (or Maesygarnedd), Llanbedr in Merionethshire, Wales. Jones is often surnamed as Maesygarnedd, after the location of his residence in North Wales, and spoke Welsh with his family. During the English Civil War, Jones served in the Parliamentarian forces in Wales, and was described as a colonel in 1646 while negotiating the surrender of Anglesey in June 1646. In 1648, Jones helped to suppress Sir John Owen's rising, and was thanked by the House of Commons for his share in the reconquest of Anglesey, and was voted £2,000 on account of his arrears of pay. He was returned to the Long Parliament in about 1647 for Merionethshire.

Evidence profile

Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Jul 3, 2026. The linked authority identifier is Q6242062. VIAF identifies the subject as 30588711.

Critical limits

Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
