(?1704–1788), playwright. Born in Dublin and educated at TCD. His works include The Triumvirate (1764), a bawdy novel, and Variety (1782), a comedy performed at Drury Lane. Griffith collaborated successfully with his wife Elizabeth in A Series of Genuine Letters between Henry and Frances (1757), a novel derived from their amorous correspondence. Two sequels, Delicate Distress (1769) by ‘Frances’ and The Gordian Knot (1770) by ‘Henry’, were written independently. A son, Richard (d. 1820), was a member of the Irish Parliament, while his son, Sir Richard Griffith (1784–1878), devised ‘Griffith's valuation’, the system adopted for rating agricultural property. On ‘Henry’ and ‘Frances’, seeEscape from the Anthill (1985) by Hubert Butler, who inherited their house at Bennetsbridge.
