Thomas Fleming, 10th Baron Slane

Thomas Fleming (died 1601) was an Irish peer, and a member of the Parliament of Ireland of 1585. He was the son of James Fleming, and great-grandson of James Fleming, 7th Baron Slane. His mother was Ismay Dillon, daughter of Sir Bartholomew Dillon, Lord Chief Justice of Ireland and his first wife Elizabeth Barnewall.^[1]

He succeeded to the barony after the death of his cousin , whose marriage to Alison Dillon, daughter of Sir Robert Dillon, failed to produce an heir. He was the only Irish nobleman to serve with Walter Devereux, 1st Earl of Essex against Turlough Luineach O'Neill, head of the O'Neill dynasty and the effective ruler of Ulster, in March 1574. He was one of the leaders of the opposition to the policies of Sir John Perrot, the Lord Lieutenant of Ireland, in the 1580s. Despite this he was regarded as a loyal servant of the English Crown, and enjoyed the personal regard of Queen Elizabeth I.^[2]

He married Catherine Preston, daughter of Jenico Preston, 3rd Viscount Gormanston and Lady Catherine FitzGerald.^[3] They had three daughters, Katherine, Margaret and Eleanor. Later Barons of Slane were descended from Eleanor, who married her father's heir, her cousin William, 11th Baron Slane, son of George Fleming, another descendant of the 7th Baron, and his wife Mary Cusack. Her sister Katherine married Piers FitzThomas Butler, illegitimate son of Thomas Butler, 10th Earl of Ormonde. Their descendants held the title Viscount Galmoye. Margaret married John D'Arcy.^[4]
