Charles MacCarthy, 1st Viscount Muskerry

Sir Charles MacCarthy, 1st Viscount of Muskerry (died 1641), also called Cormac Oge, especially in Irish, was from a family of Irish chieftains who were the Lords of Muskerry, related to the Old English through maternal lines. He became the 17th Lord of Muskerry upon his father's death in 1616. He acquired a noble title under English law, becoming 1st Viscount Muskerry and 1st Baron Blarney under letters patent. He sat in the House of Lords in both Irish parliaments of King Charles I. He opposed Strafford, the king's viceroy in Ireland, and in 1641 contributed to his demise by submitting grievances to the king in London. Muskerry died during this mission and was buried in Westminster Abbey.
