In 1788 Dr. Hales resigned as professor having been appointed Church of Ireland rector of Killeshandra, County Cavan the year before, and lived there for the rest of his life. In 1791 he married and he and his wife had two sons and two daughters. In 1798 he obtained government troops to regain control of the country round Killeshandra, following the landing by a French army at Killala. From about 1812 was chancellor of the diocese of Emly.

His best-known work is A New Analysis of Chronology, which took twenty years to complete and was finally published in three volumes (1809 - 1812). In this book, which deals with the chronology of the whole Bible, Hales made it his rule as far as possible to use original sources. His other works include The Inspector, or, Select Literary Intelligence for the Vulgar and Irish Pursuits of Literature (both 1799), Methodism Inspected (1803–5), and Letters on the Tenets of the Romish Hierarchy (1813). From about 1820 or earlier he suffered from depression. He died in 1831.
