TROY, JOHN THOMAS. - Bishop, b. at Porte-town near Dublin on 10 May 1739, d. in Dublin on 11 May 1823.
In 1755 he entered the Dominican Order in Rome, taught theology and canon law, and was rector of S. Clemente entrusted to the Irish Dominicans. Appointed bishop of Ossory in 1776, he maintained an attitude favourable to the constituted authorities. Archbishop of Dublin in 1786, he supported the English unionist project and convinced the other bishops to abandon the neutrality they had initially maintained on this question. In 1795 he founded the ecclesiastical institute of Maynooth, and in 1815 he laid the first stone of Dublin cathedral.
