Cadwallader, David a Methodist Episcopal minister, was born in Montgomeryshire, North Wales, May 28,1791. He was converted and joined the Methodists in 1812; began preaching in 1814; and emigrated to Delaware County, O., in 1821, where he labored as a local preacher till 1828, when he joined the Ohio Conference, and was sent as Welsh missionary to Oneida County, N. Y. Three years later he returned to Delaware County, labored one year in the Ohio Conference, and then, on account of the small salary that he had been receiving, was obliged to locate in order to support his family. He labored successfully as a local preacher 'until 1844, when he re-entered the Ohio Conference, and for four years travelled extensively through Ohio and Pennsylvania. In 1848 he was stationed at Pittsburgh, 'Pa., and in the following year, when many preachers fled the city on account of the terrible pestilence that raged there, Mr. Cadwallader was always found at his 'post, not only among his own people, but among others. Failing health obliged him to become a supernumerary in 1854, and he retired to his home in Delaware County, O., where he died. Oct. 19, 1855. See Minutes of Annual Conferences, 1856, p. 113.
