Aaron Crossley Hobart Seymour

Seymour, Aaron Crossley Hobart, son of John Crossley Seymour, M.A., Vicar of Cahirelly, Diocese of Cashel (and elder brother of the Rev. Michael Hobart Seymour, author of several works on the Roman controversy), was born in the county of Limerick, Dec. 19, 1789. From an early age he gave much attention to literary pursuits, and at the age of 21 he published his Vital Christianity exhibited in a Series of Letters on the most Important Subjects of Religion, addressed to Young Persons, 1810. This work, written during an illness, contains several of his hymns and other poetical pieces. He also edited a new edition of Dr. Gillies's Life of Whitefield, and wrote a "Memoir," which was prefixed to the Reliques of Ancient Irish Poetry, by Miss Charlotte Brooke, 1816. His most important work was his Life and Times of Selina, Countess of Huntingdon, 2 vols., 1839. He resided for some time in Naples (circa 1839-1847), and then at Bristol. He died Oct., 1870. A few of his hymns are still in common use, including "Jesus, Immortal King, arise," and others.
