Henry was the son of John Onderdonk and Deborah Ustick, and husband of Elizabeth Carter.
He was educated at Columbia College. Taking Holy Orders, he was for some time rector of St. Ann’s Church, Brooklyn, New York.
In 1827, he was consecrated in Philadelphia, Pennsylvania, and served as assistant bishop to Bishop White; he succeeded White upon White’s death in 1836.
The House of Bishops suspended him 1844, charging intemperance, but he was restored in 1856.
He served on the committee which compiled the 1826 Prayer Book Collection, and was by far the largest contributor thereto.
