William Windham (of Earsham, junior)
William Windham was a British landowner and politician.
The eldest son of William Windham of Earsham and Anne Tyrrell, he came of an old Norfolk family. He is sometimes called William Windham Ashe, a misnomer according to the History of Parliament. On his father's death he inherited Earsham Hall in Earsham, Norfolk.
He served as sub-governor to Duke of Cumberland in 1731 and was afterwards Comptroller of the Duke's Household till the Duke's death in 1765. He was elected a Fellow of the Royal Society in 1749 although his fellowship lapsed after only two years.
He entered Parliament for the nearby borough of Aldeburgh in 1747, for which he sat until 1761. He briefly returned to Parliament for Helston from 1766 to 1768.
Upon his death in 1789, Earsham Hall went to his nephew, Joseph Wyndham-Bower. In April 1734, he had married Mary, Dowager Countess of Deloraine, daughter of Capt. Charles Howard and granddaughter of Col. Philip Howard, but the two had no children.
