Trench (Heywood)

The Trenchs of Garbally, county Galway, from whom the Heywood, county Laois branch are descended, bought lands in the baronies of Carra and Gallen, county Mayo, from the Brownes of Westport at the end of the 17th century. In 1833 the Trenchs of Heywood sold their county Mayo estate to Sir Compton Domvile of Templeogue and Santry, county Dublin, for £60,000. Sir C. Domvile had married Helen Sarah Trench of Heywood in 1815. Sir Frederick William Trench (1777-1859) of Heywood, an army officer and politican, owned a large estate in county Roscommon, in the parishes of Taghboy, Kiltoom, Kilmeane, Taghmaconnell and Dysart, barony of Athlone. When he died he left his Irish property to his eldest sister, the wife of Sir C. Domvile.
