Donough MacCarthy
MacCarthy, Donough, Viscount Muskerry, Earl of Clancarty, grandson of preceding, devoted himself to the defence and assertion of the religion of his ancestors. He married a sister of the Duke of Ormond. He was one of the generals in Munster in the War of 1641-'52, and was among the last to lay down his arms in the final conflict — being defeated by Ludlow in Kerry, in June 1652, and upon the 27th of that month obliged to surrender his last stronghold, Ross Castle, Killarney, and his army of 5,000 men. He then passed into Spain. Charles II. created him Earl of Clancarty, and his estates were restored to him by Act of Parliament. He died in London, August 1665.
