Charles, son of John Moore, 1st Baron Moore, and Mary Lum, daughter of Elnathan Lum, was educated at Trinity College, Dublin, and succeeded
his father as 2nd Baron in 1725, being created 1st Earl of Charleville in 1758. He served as Governor and Custos Rotulorum of King's County.
His marriage to Hester Coghill was childless and so on his death in
1764 he left his estates to John Bury, for whose son Charles the title of Earl of Charleville was recreated in 1806.
