He was the eldest surviving son of Stephen Moore, member of the Irish Parliament for County Tipperary, who had been created Baron Kilworth, of Moore Park in the County of Cork, in 1764 and Viscount Mount Cashell, of the City of Cashell, in 1766. These titles were also in the Peerage of Ireland. The first Earl was succeeded by his eldest son, the second Earl. He sat in the House of Lords as an elected Irish Representative Peer from 1815 to 1822. His eldest son, the third Earl, was an Irish Representative Peer from 1826 to 1883. He was succeeded by his elder son, the fourth Earl, who in his turn was succeeded by his younger brother, the fifth Earl. The titles became extinct on the death of the sixth Earl in 1915.
