Though not numerous in Ireland the name Troy is not uncommon in Co. Tipperary and surrounding areas. The location of this small sept (which originated in Co. Clare but did not remain there) was in the Clogheen district of Co. Tipperary: their association with that part of the country is perpetuated in the place-name Ballytrehy. O'Trehy is an older anglicized form of the name is use as late as the seventeenth century, but now very rare: O'Trehy is a phonetic rendering of the Irish O Trioighthigh, presumably derived from the Irish word Trioghtheach meaning a foot-soldier. The name in the 1659 census is spelt Trohy and it appears among the more numerous names in the baronies of Eliogarty and Ikerrin, Co. Tipperary. Another place-name is Castletroy, now a suburb of Limerick. The name was closely associated with that city and appears very frequently in its earliest records. Henry Troy was Provost of Limerick in 1197. In 1198 the first mayor and sheriffs were chosen: between that date and 1463 no less than twenty-one Troys held one or another of those offices. The best known Irishman so called was Most Rev. Thomas Troy (1739-1823), Archbishop of Dublin: he was noted for his strong and forcibly expressed views in opposition to popular Irish sentiment, e.g. his censure of the priests who took part in the 1798 Rising, his denunciation of the Whiteboys and his advocacy of the Union; he was also a co-founder of St. Patrick's College, Maynooth. The well-known American painter of horses was not of this stock: his father was a Frenchman called de Troye, and this family is also found in Ireland, where it has been gaelicized as de Treo.
