Justin McCarthy, Viscount Mountcashel

Justin was born about 1643,{{Sfn|Murphy|1959|p=49|ps=. "I have been unable to determine the precise date of his [Justin's] birth: the year 1643 is an approximation arrived at ..."}} probably in Blarney, County Cork, Ireland.{{Sfn|Murphy|1959|p=1|ps=. "Justin was born about 1643, most probably in Blarney ..."}} He was the third son of Donough McCarthy and his wife Eleanor Butler. At the time of his birth, Justin's father was the 2nd Viscount Muskerry, but he would be advanced to Earl of Clancarty in 1658.{{Sfn|Cokayne|1913|p=[https://archive.org/details/completepeerageo03coka/page/215/ 215, line 2]|ps=. "As reward for his services he was by patent dat. at Brussels 27 Nov., 1658, cr. Earl of Clancarty, co. Cork [I.

Justin was born during the Irish Confederate Wars in the part of Ireland that was then held by the Irish confederacy. His father was then a member of the confederacy's Supreme Council and commander of its Munster army. Justin was two in 1645 when his mother hosted Giovanni Battista Rinuccini, sent as nuncio to Ireland by Pope Innocent X, at Macroom Castle.{{Sfn|Meehan|1882|p=[https://archive.org/details/confederationki01meehgoog/page/n154/ 136]|ps=. "At the great gate of Macroom Castle he was received by the Lady Helena Butler, sister to Lord Ormond and wife of Lord Muskerry, who was then in Dublin."}} His father opposed Rinuccini's dealings in Irish politics and when the nuncio seized power in a coup d'état in 1646, Justin's father was detained at Kilkenny Castle and stripped of the command of the Munster Army.{{Sfn|Meehan|1882|p=[https://archive.org/details/confederationki01meehgoog/page/n214/ 196]|ps=. "... chose a new council composed of four bishops and eight laymen with himself as president."}}{{Sfn|Carte|1851|p=[https://archive.org/details/lifeofjamesdukeo03cart/page/266/ 266]|ps=. "... on the 26th [September 1646] by a solemn decree appointed a new council consisting of four bishops and eight laymen ..."}}

In April 1650 his family lost Macroom Castle, where Justin had spent his childhood, in the context of the Battle of Macroom.{{Sfn|Adams|1904|p=[https://archive.org/details/castlesofireland00adamiala/page/290/ 290]|ps=. "Upon approach of Lord Broghill with a body of horse, the garrison in the castle set fire to it and joined the main body encamped outside."}}{{Sfn|Bagwell|1909|p=[https://archive.org/details/irelandunderstua02bagw/page/223/ 223]|ps=. "... they burned Muskerry's castle at Macroom and assembled in the park. They were raw levies and probably badly armed, for they were routed in a very short time."}}{{Sfn|Bagwell|1909|p=[https://archive.org/details/irelandunderstua02bagw/page/223/ 223, in the margin]|ps=. "Battle of Macroom, 10 April 1650"}} Around that time, anticipating the loss of Macroom or because of it, his father sent Justin, his mother, and sisters to security in France. His mother then lived in Paris, in the convent of the Feuillantines.{{Sfn|Clark|1921|p=[https://archive.org/details/anthonyhamiltonh00claruoft/page/8/ 8]|ps=. "... his [Anthony Hamilton's] mother and his aunt, Lady Muskerry, had apartments at the couvent des Feuillantines in Paris ..."}}

After Rinuccini's departure, his father fought the Parliamentarians in the Cromwellian Conquest of Ireland. Muskerry fought to the bitter end, surrendering Ross Castle near Killarney to Edmund Ludlow in June 1652.{{Sfn|Ohlmeyer|2004|p=[https://archive.org/details/isbn_0198613857/page/107/ 107, right column]|ps=. "he fought on before finally surrendering at Ross Castle (27 June 1652) and fleeing to the continent."}}{{Sfn|Firth|1894|p=[https://archive.org/details/memoirsedmundlu01firtgoog/page/n396/ 320, line 10]|ps=. "Ross in Kerry; where the Lord Muskerry made his principal rendezvous, and which was the only place of strength the Irish had left, except the woods, bogs and mountains ..."}}

File:JustinMacCarty.png

In 1658 his father was created Earl of Clancarty by Charles II in Brussels, where he was then in exile. By this advancement the title of the viscount of Muskerry became a subsidiary title of the family, which was given as courtesy title to the Earl's heir apparent, at that time his eldest brother Charles, who was therefore styled Viscount Muskerry thereafter.

The family had their property confiscated under the Cromwellian regime, but it was restored to them at the Restoration of Charles II. Justin seems to have grown up mainly in France. He became a professional soldier and showed great skill in his profession, but poor eyesight hampered his career. He entered the French army in 1671, and then transferred to the Duke of Monmouth's regiment, then in French pay, and served against the Dutch.{{Cite journal|journal=Journal of the Cork Historical and Archaeological Society|volume=13|series= Second Series|year=1907|page=157|last=Coleman|first=James|title=Justin MacCarthy, Lord Mountcashel}}

On 4 March 1665, the Second Anglo-Dutch War broke out. Three months into the war, on 3 June 1665 O.S., his brother Charles, Lord Muskerry, was killed on the flagship, the Royal Charles, in the Battle of Lowestoft, the first major naval engagement of the war and an English victory. His brother had an infant son, also named Charles, who succeeded him as heir apparent and was, therefore, styled Viscount of Muskerry. However, their father, the 1st Earl, died two months later, on 4 August 1665,{{Sfn|Cokayne|1913|p=[https://archive.org/details/completepeerageo03coka/page/215/ 215, line 6]|ps=. "He [the 1st Earl] d. in London, 4 Aug. 1665."}} and the younger Charles succeeded as the 2nd Earl of Clancarty. The 2nd Earl died about a year later, on 22 September 1666, still an infant.{{Sfn|Cokayne|1913|p=[https://archive.org/details/completepeerageo03coka/page/216/ 216, line 4]|ps=. "... d. [died] an infant, 22 Sep. 1666."}}{{Sfn|Burke|1866|p=[https://archive.org/details/agenealogicalhi00burkgoog/page/n360/ 344, right column, line 42]|ps=. "Charles, 2nd earl, who d. [died] a child, in 1668, and was s. [succeeded] by his uncle Callaghan, 3rd Earl."}}{{Efn|{{harv|Cokayne|1913}} states he died on 22 September 1666, whereas {{harv|Burke1866}} states that he died in 1668.}} Thereupon Callaghan, the infant's uncle, succeeded as the 3rd Earl of Clancarty.

Justin McCarthy came to England in 1678 and was befriended by the future James II, who generally chose soldiers, especially Irish soldiers, as his boon companions. Charles II decided to use his services in Ireland, and made him a colonel in Sir Thomas Dongan's regiment. On the outbreak of the Popish Plot, however, the discovery of Colonel McCarthy's presence at Whitehall caused uproar: he fled the country, and the Secretary of State, Sir Joseph Williamson, who had issued his commission, was sent to the Tower of London.{{Sfn|Kenyon|1972|p=[https://archive.org/details/popishplot00jpke/page/103/ 103]|ps=. "... but on November 8 [1678] one of theses officers, Colonel Justin MacCarthy, was found strolling outside the House of Commons, brought in and questioned and sent out of London."}}

By 1683 Colonel MacCarthy was at Court again, where his growing influence was shown by the marriage he arranged for his immensely wealthy nephew Donough MacCarthy, 4th Earl of Clancarty. Callaghan, the 3rd Earl, had died in 1676, leaving his young son in the care of his widow, Lady Elizabeth FitzGerald, daughter of George FitzGerald, 16th Earl of Kildare: she has been described as "a fierce Protestant isolated in a Catholic family".{{Sfn|Kenyon|1958|p=[https://archive.org/details/robertspencerear0000keny/page/102 102, line 8]|ps=. "His mother, a fierce Protestant isolated in a Catholic family ..."}} She placed her son in the care of John Fell, Bishop of Oxford, for a Protestant education. Colonel MacCarthy was determined to have the final word on the young earl's marriage and religion, and persuaded the King to invite the young earl to Court for Christmas. He brought that letter in person to the bishop.{{Sfn|Kenyon|1958|p=[https://archive.org/details/robertspencerear0000keny/page/102 102, line 15]|ps=. "... on 18 December 1684 Colonel MacCarthy presented himself at Christ Church with a royal letter, countersigned by Sunderland, signifying the king's will and pleasure that the Clancarty should attend the Christmas festivities at White Hall."}} Here Donough MacCarthy, at sixteen, was married to Elizabeth Spencer who was two years younger. The marriage would not be consummated for many years. The bride was a daughter of Robert Spencer, 2nd Earl of Sunderland. The Earl of Sunderland was a Protestant at that time but had Catholic leanings and would turn a Catholic in 1687. The marriage was a failure, and Kenyon, Sunderland's biographer, remarked that it left a stain on the reputation of all those who ruined the lives of these two young people, without gaining anything in return. Gilbert Burnet wrote that in anything that did not directly concern his religion, MacCarthy was an honourable man.{{Sfn|Burnet|1833|p=[https://archive.org/details/bishopburnetshi08burngoog/page/n464/ 458, line 25]|ps=. "Lord Clancarty had an uncle Col. Maccarty, who was in most things, where his religion was not concerned, a man of honour"}}

Under the Catholic King James II, McCarthy was in 1686 promoted to Major General and became a member of the Privy Council of Ireland.{{Sfn|Wauchope|2004|p=[https://archive.org/details/isbn_0198613857/page/111/mode/2up 111, right column, line 21]|ps=. "... he was in 1686 made a privy counsellor and promoted to major-general."}} He quarrelled with the Lord Lieutenant of Ireland, the 2nd Earl of Clarendon, and probably intrigued to secure Clarendon's recall.

In 1688 or early in 1689, Tyrconnell appointed him Muster-Master General in the Irish Army and Lord Lieutenant of County Cork.{{Sfn|Webb|1878|p=[https://archive.org/details/acompendiumiris00webbgoog/page/n312/ 304, left column, line 7]|ps=. "In 1688 or early in 1689 he was appointed by Tyrconnell Muster-Master General and Lord lieutenant of the County of Cork."}}

On 23 May 1689, James II elevated Justin McCarthy to being Viscount Mountcashel, with the subsidiary title of Baron Castleinch.{{Sfn|Cokayne|1893|p=[https://archive.org/details/completepeerage05cokahrish/page/n391/ 390, line 18]|ps=. "he was cr. [created] 23 May 1689 ... Baron Castleinch and Viscount Mountcashell, both in the co. Tipperary, [I. [Ireland]]."}} These titles were in what later became known as the Jacobite peerage.

Later in 1689, Lord Mountcashel, as he was now, took Castlemartyr and Bandon for James;{{Sfn|Webb|1878|p=[https://archive.org/details/acompendiumiris00webbgoog/page/n312/ 304, line 11]|ps=. "He took Castlemartyr and Bandon from the Protestant party ..."}} at Bandon there was a massacre called "Bloody Monday", but Mountcashel persuaded the King to issue a general pardon to his defeated opponents. He met James II at his landing at Kinsale, and was commanded to raise seven regiments. He sat in the Irish House of Lords in the Parliament of 1689.

With 3,000 men he advanced from Dublin towards Enniskillen,{{Sfn|Harris|1747|p=[https://books.google.com/books?id=khSVC0eZuwAC&pg=282 282]|ps=. "In July 1689, a numerous and well-appointed Army was led from Munster under the Conduct of Justin Mac-Carthy ... "}} which with Derry was one of the two places still resisting James II. He was met by 2,000 Protestant 'Inniskilleners' at the Battle of Newtownbutler on 31 July 1689. Mountcashel's forces were routed; he was wounded, then captured.{{Sfnp|Webb|1878|p=[https://archive.org/details/acompendiumiris00webbgoog/page/n312/ 304, left column, line 23]|ps=. "Viscount Mountcashel was miserably defeated at Newtownbutler on 31st July."}} Allowed out on parole he broke parole and escaped to Dublin; Schomberg remarked that he had thought McCarthy was a man of honour, but on the other hand he expected no better from an Irishman.{{Sfnp|Webb|1878|p=[https://archive.org/details/acompendiumiris00webbgoog/page/n312/ 304, left column, line 38]|ps=. "I took Lieutenant-MacCarthy to be a man of honour', remarked Schomberg on hearing of his escape 'but would not expect that in an Irishman any more.'"}}

He went into exile in France and commanded the first Irish Brigade of Louis XIV.

He married Lady Arabella Wentworth, daughter of Thomas Wentworth, 1st Earl of Strafford and his second wife Lady Arabella Holles, who was many years older than himself; they had no documented or legally recognized children; however, it is believed his lineage continued.

His later career was hampered by his near-blindness. He died on 1 July 1694 N.S. at Barèges where he had gone to take the waters for his health and was buried there.{{Sfn|Cokayne|1893|p=[https://archive.org/details/completepeerage05cokahrish/page/n391/ 390, line 27]|ps=. "He d. s.p. [died without issue] 21 July 1694 at the baths at Barèges when all his honours became extinct."}}{{Sfn|Wauchope|2004|p=[https://archive.org/details/isbn_0198613857/page/112/ 112, right column, line 10]|ps=. "He died there [at Barèges] on 1 July 1694, and was buried there."}}{{Sfn|Ruvigny|1904|p=[https://archive.org/details/jacobitepeerageb00ruvi/page/124/ 125]|ps=. "He died s.p. [without issue] 1st July 1694 at the baths at Barèges ..."}} At his death he tried to leave his property to a cousin, but it passed to his niece Catherine, sister of the 4th Earl of Clancarty. Her husband, Paul Davys, had the title Viscount Mount Cashell revived in his own favour.{{Sfn|Cokayne|1893|p=[https://archive.org/details/completepeerage05cokahrish/page/n391/ 390, line 36]|ps=. "[Paul Davys was] cr. [created]; 31 Jan. 1705/6 Viscount and Baron Mountcashel, co. Tipperary, [I. [Ireland]]."}}
