Cuny’s origins are obscure. His father, Walter, was probably the gentleman usher of the same name who served in Henry VIII’s Household and moved from Staffordshire to Pembrokeshire.
In 1591 Cuny commanded a newly raised infantry company.
By 1597 Cuny was back in Ireland, this time commanding a company at Carlingford. By June of the following year he had been granted his own regiment and the position of sergeant-major of the Army. In August 1599 he led the rearguard when forces under Sir Henry Bagnall† attempted to relieve the besieged garrison of the Blackwater Fort. Surprised at the Yellow Ford while strung out along their line of march, the English were overwhelmed. Bagnall was killed, having ignored the advice of Cuny and another colonel to lead the main body rather than the vanguard,
In February 1601 Cuny was arrested in London on suspicion of involvement in Essex’s rising, as was Essex’s steward for Welsh lands, (Sir) Gelly Meyrick†. Under interrogation, Meyrick protested that Cuny had only come up to London to lobby for an addition to the Pembrokeshire property he leased from Essex and to petition the Council for payment of his arrears. As the Council could not disprove Meyrick’s story, or ignore the fact that Cuny’s military career had been ruined by Essex himself, Cuny was not surprisingly released.
Cuny was returned for Pembroke Boroughs in 1604. By then he was settled at St. Florence, six or seven miles south-east of Pembroke and a couple of miles west of Tenby, one of the constituency’s contributory boroughs. He undoubtedly owed his election to Pembroke’s mayor, the lawyer Nicholas Adams†, an ally of the Meyricks and thus a former member of the Devereux faction in south Wales.
Cuny’s connection with the Devereux family did not cease with the execution of the 2nd earl of Essex in 1601. Indeed, on 18 May 1607 he was appointed deputy constable of Tenby Castle by the castle’s joint constables, the 3rd earl of Essex and Lord Howard de Walden (Theophilus Howard*). However, his links with the Devereux were not as strong as he would have wished, for at around the same time he failed to obtain the lease of the Devereux manor of Lamphey, which adjoined his property at St. Florence, and which was awarded instead to one Rhys Phillips Scarfe. A furious Cuny subsequently endeavoured to have Scarfe evicted with the aid of his brother-in-law Adams. Cuny and his henchmen also allegedly beat and threatened Scarfe’s servants in the hope that Scarfe would default on his rent. These bullying tactics paid dividends, for in December 1609 Essex’s paternal grandmother, Lettice, countess of Leicester, who held Lamphey in trust for the earl’s half-brother, Walter Devereux*, finally lost patience with Scarfe and reassigned the lease to Cuny. Armed with this document, and a warrant issued by Common Pleas, Cuny and his servants stormed Lamphey in June 1610, manhandled and evicted Scarfe’s wife Alice and allegedly seized goods worth £800. Seven years later Alice recounted her story before Star Chamber, but to no avail.
Cuny first served as mayor of Pembroke in 1616. During his second term of office he and his deputy, Nicholas Adams, ensured that their brother-in-law Lewis Powell, to whom Cuny had recently transferred the lease of Lamphey, was returned to the 1621 Parliament for Pembroke Boroughs.
Following the transfer of his lease of Lamphey to Powell, Cuny moved to Pembroke where, by 1625 at the latest, he leased some property belonging to the Crown.
Cuny died in October 1627. In his will he stipulated that the revenues arising from the leases of four Pembrokeshire farms and land in Pembroke were to be applied to the maintenance of his only son Walter, who fought for Parliament in the 1640s.
