The constituency of Flint Boroughs comprised the shire town and four out-boroughs, of which the largest was Rhuddlan in the county’s north-western corner, with a population by 1670 of approximately 800.
In the elections to the Short Parliament, the Boroughs returned Sir Thomas Hanmer of Hanmer on 9 March 1640. Successive heads of the family, including Hanmer’s father, had sat for Flintshire or the Boroughs since the mid-sixteenth century, and their extensive estate in and around Hanmer, near Overton, gave them a powerful interest in the Maelor.
The Flint Boroughs election indenture for the Short Parliament is badly faded but appears to employ much the same layout and wording as its successors for the Long Parliament in which the returning parties were a group of named burgesses and ‘many other freemen of the borough of Flint and the other boroughs in the county’. There were at least 15 signatories from at least four of the boroughs – Caerwys, Caergwrle, Flint and Rhuddlan.
In the election to the Long Parliament, which was held at Flint on 19 October 1640, Hanmer’s place was taken by Salusbury, who belonged to a cadet branch of western Denbighshire’s leading family, the Salusburys of Lleweni.
Salusbury sided with the king in the civil war and was disabled from sitting as an MP in February 1644.
Disenfranchised under the Instrument of Government in 1653, Flint Boroughs regained its seat in the elections to Richard Cromwell’s* Parliament of 1659, to which it returned John Hanmer, son of Sir Thomas. The indenture has not survived. Hanmer was superseded in the elections to the 1660 Convention by the dedicated Flintshire royalist Roger Whitley, who would be returned for the Boroughs again to the Cavalier Parliament and the first and second Exclusion Parliaments.
Right of election: in the freemen of Flint, Caergwrle, Caerwys, Overton and Rhuddlan.
