William Handcock, 1st Viscount Castlemaine
William Handcock, 1st Viscount Castlemaine, PC (Ire) (28 August 1761 – 7 January 1839) was an Irish MP and supporter of Union with Great Britain.
He was born in Dublin, Ireland to Reverend Richard Handcock and Sarah Toler. In 1783, Handcock stood for Athlone in the Irish House of Commons and represented the constituency until the Act of Union in 1801. He was Constable and Governor of Athlone 1813–1839 and Governor of County Westmeath 1814–1831.
On 20 March 1782 he married Lady Florinda Trench (3 August 1766 – 9 February 1851), born in Twyford, Westmeath to William Power Keating Trench, 1st Earl of Clancarty and Anne Gardiner, Countess of Clancarty. William and Florinda had no children, and when Handcock was created Baron Castlemaine (in the Peerage of Ireland) on 21 December 1812 the title had a special remainder "failing heirs of his body to his brother". He was further created Viscount Castlemaine on 12 January 1822 but without a special remainder. On his death his viscountcy became extinct and his barony passed to his brother whose descendants still hold the title.
