Biography

Justin McCarthy was the younger son of Donough MacCarty, 1st Earl of Clancarty, from the MacCarthy of Muskerry dynasty who had lands in County Desmond. His mother was Lady Eleanor Butler, sister of James Butler, 1st Duke of Ormond.

Justin married Lady Arabella Wentworth, daughter of Thomas Wentworth, 1st Earl of Strafford and his second wife Lady Arabella Holles.

Arabella, was many years older than Justin.

They had no children. However It is said that McCarthy had one child with a lady of the night named Elizabeth Billington.[citation needed] The childs name was Catherine.

Justin was created Viscount Mountcashel and Baron Castleinch by James II in 1689, after James's exclusion as King of England (but unlike most Jacobite peerages, the title was enrolled).

He died 21 July 1694 at Barege, France. [1] At his death he tried to leave his property to a cousin, but much of it seems to have come to his niece, another Catherine, sister of the 4th Earl of Clancarty. Her husband, Paul Davys, had the title Viscount Mount Cashell revived.[2]

McCarthy was a charismatic individual who had been brought up in France when his father, Donough McCarthy, had left Ireland in the 1650’s because he had incurred the wrath of Oliver Cromwell and it would have been unhealthy for him to remain in Ireland. The confiscated McCarthy estates were returned after the restoration of the crown in England. However when the infamous Titus Oates accused numerous Catholic peers of plotting to murder King Charles II Mountcashel emulated his father and returned to the safety of France. It was a wise decision on his part. More than 20 alleged conspirators were executed before Oates was found guilty of perjury. Although Mountcashel commanded Louis’ Irish Brigade his service to French King was hampered by chronically bad eyesight and a wound received while fighting in the south of France. He died in 1694.[3]
Notes

Based on the information quoted, it seems unlikely that Denis Mccarthy is the son of Justin and Arabella.
