It is reputed that a later occupant of Plas Uchaf was Colonel John Jones, who’s second marriage was to the sister of Oliver Cromwell. Until about 1904 a picture of Oliver Cromwell hung in the hallway at Plas Uchaf. Brother-in-law of Oliver Cromwell, Jones was born at Llanbedr in North Wales and is often surnamed Jones Maesygarnedd after the location of his Merionethshire estate. He was an avid Republican at a time when most of Wales was Royalist, and for this reason he was described by one of his contemporaries as “the most hated man in North Wales”.
During the civil war Jones served in the parliamentary forces in Wales, and was described as a colonel. He was returned to the Long Parliament in about 1647 for Merionethshire. Jones was selected as one of the judges of King Charles I, and attended the trial with great regularity up to the day he signed the King’s death-warrant.
