The representation of these boroughs was controlled by the local squires. Sir John Glynne retained the seat without opposition until his death in 1777;1 and was succeeded by Watkin Williams, of an influential Flintshire family, whose father had represented the constituency 1742-7. Thomas Hanmer, son of Sir Walden Hanmer, issued an address in 1777 but did not stand; and there seems to have been no opposition to Williams in 1780 or 1784.
