The Salusburys, who settled at Lleweni, Denbighshire in the fourteenth century, were undoubtedly English in origin, but they soon intermarried with their Welsh neighbours. By the time of the 1536 Union they were the leading family in the vale of Clwyd, dominating the parliamentary representation of the new county of Denbighshire until 1558. The local influence of the senior branch of the family dwindled during Elizabeth’s reign, partly because of their association with the earl of Leicester’s unpopular regime in Denbigh lordship, and partly because the head of the family, Thomas Salusbury, was executed as an accomplice to the Babington Plot in 1586.
The Hawarden parish register noted that John Salusbury was an ‘infant’ at his marriage in 1599; he was probably around seven years old. The match was presumably intended to cement an alliance with the Ravenscrofts, an influential Flintshire family with connections to the lord keeper, Sir Thomas Egerton†, but it is difficult to explain why the ceremony was not postponed until the parties were older.
While his father had no known parliamentary ambitions, Salusbury was the successful contender in the most keenly fought Flintshire election of the early Stuart period, winning the county seat in 1626 in a contest with Sir Thomas Hanmer†, 2nd bt. At the preceding election in April 1625 Salusbury had signed the indenture returning Hanmer’s uncle Sir John Trevor II, which suggests that he then supported Trevor against a challenge from Sir Thomas Mostyn.
Having decided to stand, Salusbury doubtless counted upon the support of his wife’s family, the Ravenscrofts, and his neighbours, particularly Sir Peter Mutton*. He may even have hoped that Sir Thomas Mostyn could bring the Mostyn freeholders over to his side, although it seems that Sir Roger ultimately threw in his lot with Trevor and Hanmer. The key factor may well have been the support of the sheriff, Thomas Evans, who allegedly boasted at the county court ‘that how many soever here, yet is the election in my power. I may choose whom I will’. The prospect of defeat may have panicked Salusbury’s opponents, who probably only substituted the 13-year old Hanmer as their candidate on the eve of the election to save Trevor from the embarassment of defeat. On the day of the election itself Salusbury’s supporters allegedly claimed ‘that their master would have it by the sword if he could not otherwise have it’, but they were not required to carry out their threat, as the sheriff held a two-day poll, presumably using the time to disqualify a sufficient number of Hanmer’s freeholders to ensure Salusbury’s return.
Salusbury received only a single mention in the records of the Parliament, which, predictably, concerned the conduct of the Flintshire election. His opponents petitioned about the sheriff’s misconduct, but the case, probably delayed by the proceedings against the duke of Buckingham, was not reported until 5 May. The committee had originally proposed to give sheriff Evans a month’s notice to attend the House to answer the charges brought against him but, apparently at Salusbury’s suggestion, it was agreed he should appear before the committee somewhat earlier, on 23 May. The case is not known to have proceeded any further before the dissolution of 15 June.
Salusbury played a relatively modest part in local affairs during the 1630s, perhaps largely because of his involvement in the management of the Lleweni estate after the death of his nephew Sir Henry Salusbury, 1st bt. in 1632.
