Lieutenant-General William Cadogan, 1st Earl Cadogan KT, PC (c. 1671-1726) was an Irish-born British Army officer. He began his active military service during the Williamite War in Ireland in 1689 and ended it with the suppression of the 1715 Jacobite Rebellion.

Early life[edit]
Cadogan was born in Ireland around 1671, the son of the barrister Henry Cadogan and his wife Bridget Waller, daughter of the regicide Sir Hardress Waller. His family were Irish Protestants of Welsh descent. William's grandfather William Cadogan served as an officer in Oliver Cromwell's New Model Army.
He was one of five children, including two brothers Ambrose and Charles and two sisters: Frances, who died young, and Penelope, who married Sir Thomas Prendergast, 1st Baronet.[1] The family owned an estate at Liscarton in County Meath. His father served as High Sheriff of the county and also acquired property in County Limerick.
At the age of ten, he was sent to England to be educated at Westminster School, then run by Richard Busby. William's father intended him to take up a law career like himself and, in March 1687, he was accepted as a student at Trinity College, Dublin.[2] By this time he had developed into a tall, well-built young man.[3]
Family[edit]
He married Margaret Cecilia Munter in April 1704 at The Hague. They had two daughters: Sarah (born 18 September 1705), who married Charles Lennox, 2nd Duke of Richmond, and Margaret (born 21 February 1707), who married Charles John Bentinck, fourth son of William Bentinck, 1st Earl of Portland. With no male heir the earldom became extinct. His younger brother Charles, who had married Elizabeth Sloane, the daughter of the noted Irish-born physician and landowner Sir Hans Sloane, inherited the barony by special remainder, passing it down through his son.
