Originally from south Wales, the Vaughans acquired Llwydiarth by marriage in the fourteenth century. During the early Stuart period they owned 100,000 acres of upland pasture in northern Montgomeryshire, worth perhaps £2,500 a year, with outlying properties in adjacent parts of Denbighshire and Merioneth. Despite the size of this estate, no member of the family represented Montgomeryshire before 1647, largely because they had the misfortune to be overshadowed by the Herbert families of Montgomery Castle and Powis Castle, whose lands and local influence were even more extensive than their own.
As the fifth of seven sons, Vaughan’s chances of inheriting the family estate were initially slim. After his eldest brother, John, died without male heirs in 1616 his father modified the family entail, making the second son, (Sir) Robert, heir to the majority of his lands, and settling smaller properties on all of the others except for the future MP. This may have been a deliberate snub, but it is perhaps as likely that Vaughan was already intended for a legal career, to which end he was enrolled at the Inner Temple in 1618. Sir Robert duly succeeded to the estate upon his father’s death at the end of 1616, but was survived only by a daughter at the time of his death in 1624. Vaughan subsequently claimed that Sir Robert had created a new entail in 1622 or 1623, which settled the reversion of the estate upon him.
Two considerations ensured that the questionable validity of the 1622/3 entail vexed the Vaughan family for a generation: the first was the birth of Sir Robert’s posthumous heir, Herbert Vaughan, three weeks after his father’s death; while the second was Dame Katherine Vaughan’s ability to make her views felt through her father, Sir William Herbert* of Powis Castle, an influential figure both locally and at Court. The dispute began immediately upon Sir Robert’s death, on 30 July 1624, when Edward Vaughan and his retainers seized control of Llwydiarth, allegedly killing a servant in the process. Dame Katherine responded with a suit before the Council in the Marches, of which her father was a member, and was granted possession as guardian of the interests of her infant son. Vaughan contested this ruling in King’s Bench and Chancery, while Dame Katherine went to Star Chamber with a claim that the entail was a forgery, challenged Vaughan’s probate of her husband’s will in the Court of Delegates, and attempted to use the Court of Wards to regain control of her late husband’s goods.
Dame Katherine’s possession of the family estate left Vaughan in a very weak position, as the proportion of his brother’s goods he managed to secure hardly sufficed to cover the liability for annuities and dowries which he took on as executor of Sir Robert’s will.
Any plans Vaughan may have had for introducing an estate bill came to nothing in 1626, when the Commons neglected private legislation in favour of attacks upon the duke of Buckingham. Given his animosity towards his Herbert neighbours, he was almost certainly the ‘Mr. Vaughan’ who ‘commanded a formal presentment from Montgomeryshire against Sir William and Sir John [?Percy] Herbert’ as recusant officeholders, a motion which had earlier been rejected. He left no other trace on the records of the House, but as a Welsh MP he was entitled to attend committees for the Bromfield and Yale copyholders’ bill (1 June) and the Bulkeley estate bill (10 June).
Vaughan’s lawsuits with his sister-in-law ground on inconclusively until the eve of the Civil War. After six years of deliberation, Star Chamber ruled that the entail upon which Vaughan based his claim to Llwydiarth was not forged, but left him to pursue his claim to the estate at the Common Law, where his attempts were easily frustrated: Dame Katherine held a belated inquisition post mortem to prove her title to her late husband’s estate in 1631, which allowed her to secure a Court of Wards injunction suspending Vaughan’s suit against her. Vaughan tried to break the deadlock in the equity courts by appealing first to King’s Bench and then to the probate courts, but while Archbishop Laud offered him sympathy, he could do little to overcome rivalry between the various jurisdictions. Towards the end of the 1630s Vaughan’s adversaries added to his woes by suing him for defamation in the earl marshal’s court over his insinuation that his nephew Herbert Vaughan was illegitimate.
Vaughan is not known to have stood at either of the general elections of 1640, but, happily for him, the three courts which had done most to frustrate his cause - Star Chamber, the Court of Wards and the Marches court - all came under attack early in the Long Parliament. He quickly made his own complaint, and on 19 Mar. 1641 the standing committee for courts of justice voted to grant him immediate possession of his family’s properties in Merioneth and Denbighshire, and leave to sue for the main estates at common law. By the end of the year he was pressuring the family’s tenants to recognize him as their landlord, and he later claimed to have obtained possession of the whole estate at Common Law in August 1642.
Vaughan’s local power base on the Montgomeryshire accounts committee made him a natural ally of the Presbyterians who dominated the national accounts committee at Westminster, and it was presumably with their encouragement that he was returned as recruiter for Montgomeryshire in 1647. One of the Members arrested at Pride’s Purge on 6 Dec. 1648, he was released after two weeks, but kept under house arrest until 12 Feb. 1649. He was subsequently harassed by the Rump’s executive committees, both for his continued refusal to surrender Llwydiarth, and alleged embezzlement of £2,000 allocated to pay his garrison’s arrears at their disbandment in 1647. The worst of his problems was solved by the death of his nephew Herbert Vaughan in February 1650, and the protectoral regime confirmed his rights to Llwydiarth in 1654. Arrested in August 1659 upon suspicion of complicity with the royalist rising in Cheshire, he emerged to help with the sequestration of those, such as Myddelton, who had been in arms. Another brief period of arrest prevented him from standing for Merioneth at the general election of 1660, but in the following year he was returned for Montgomeryshire, which he represented until his death in October 1661.
Vaughan used his will to forestall any dispute over jointure rights with his erstwhile sister-in-law Dame Katherine by granting her a life annuity of £500, while he also acknowledged the £1,000 dowry he owed his nieces Magdalen and Katherine Vaughan, daughters of his long-deceased eldest brother John. These sums were to be raised from his estates by his nephew Charles Salesbury, whom he made his executor. Llwydiarth passed to a distant relative, Howell Vaughan of Glan y Llyn, Merioneth, whose son Edward represented Montgomeryshire in Parliament from 1679 until his death in 1718. The latter’s heiress united the estate with those of Plas y Ward and Gwydir by her marriage to Sir Watkin Williams Wynn of Watstay, creating an interest which was to dominate north Welsh politics in the eighteenth century.
