Beaumaris had anciently been an English town on a Welsh island, and its only competitor as a settlement to justify the description of borough was Newborough, which probably because of the encroachment of sand-drift had by the mid-sixteenth century become so impoverished as to forfeit any claim to a charter.
Beaumaris was the only Welsh borough in which the franchise was limited to the corporation, which by an Elizabethan charter of 1562 consisted of a mayor, two bailiffs and 21 capital burgesses.
Charles Jones did not live to see the Long Parliament, to which his successor as recorder, John Griffith I of Cefnamwlch, Caernarvonshire, with inherited property in Anglesey, was returned. The contracting parties on the indenture were the mayor, Thomas Bulkeley, and the two bailiffs. Twelve burgesses signed the dorse of the document.
The election was held on 22 January 1647, more than three weeks after the meeting to return Richard Wood for Anglesey. The only signatures appearing on the indenture were those of the mayor and bailiffs, suggesting that the meeting to elect William Jones, though conducted at the guildhall, may have been without even the participation of the other burgesses.
Beaumaris lost separate representation in Parliament under the Instrument of Government of December 1653, and only regained it when the council of Lord Protector Richard Cromwell* chose to re-introduce the electoral arrangements that had prevailed in 1640. The Beaumaris election took place on 13 January 1659, the same day as the election for Anglesey. The only candidate was Griffith Bodurda, son-in-law of John Griffith I, and another client of John Glynne, his brother-in-law. The indenture recorded how the burgesses had assembled between eight and eleven on the morning of the election to conclude their business, but no names were identified beyond those of the elected Member, the sheriff of Anglesey, Robert Bulkeley, and the mayor and bailiffs of Beaumaris.
