Abel, Elijah, the only colored man who is known to have been ordained to the Priesthood, was born July 25, 1810, in Maryland. Becoming a convert to "Mormonism" he was baptized in September, 1832, by Ezekiel Roberts and, as appears from certificates, he was ordained an Elder March 3, 1836, and a Seventy April 4, 1841, an exception having been made in his case with regard to the general rule of the Church in relation to colored people. At Nauvoo, Illinois, where he resided, he followed the avocation of an undertaker. After his arrival in Salt Lake City he became a resident of the Tenth Ward, and, together with his wife, he managed to Farnham Hotel in Salt Lake City. In Nauvoo he was intimately acquainted with the Prophet Joseph Smith and later in life was the especial friend of the late Levi W. Hancock. In 1883, as a member of the Third Quorum of Seventy, he left Salt Lake City on a mission to Canada, during which he also performed missionary labors in the United States. Two weeks after his return he died, Dec. 25, 1884, of debility, consequent upon exposure while laboring in the ministry in Ohio. He died in full faith of the gospel.
