James Habersham Elliott, the youngest son, was born November 22, 1819 in Charleston and graduated from the South Carolina College in 1838. Trained in the law by James L. Petigru, he was admitted to the bar in 1841. Moving to Beaufort two years later, he became a partner with Thomas Fuller, son of Dr. Thomas Fuller, in the old Richard Fuller law office, and on October 16, 1845, he married his partner's sister, Harriet Barnwell Fuller. Both Elliott and Fuller came under Dr. Walker's persuasive influence and began to study for the ministry. Thomas died before his ordination, but James was made a deacon March 4, 1849 in St. Philip's, Charleston and was ordained priest by his brother on April 15, 1851. He assisted Dr. Walker for eighteen months before being elected rector of Holy Trinity Church in Grahionville in January 1851. Two years later he became the assistant at St. Michael's in Charleston. In April 1853 Elliott and the Rev. C. P. Gadsden founded and were the joint editors of The Southern Episcopalian, a journal of general Church news, semi-monthly for the first two years and then monthly until it folded in March 1863. The Rev. Joseph A. Shanklin, who had succeeded the Rev. William Barnwell at St. Peter's, joined the editorial staff in January 1855 until his death from yellow fever in September 1856. Elliott's wife had died June 18. 1854, and he married Shanklin's widow, Catherine Ann Sadler (d. 1903), daughter of Henry Robinson Sadler and Catherine Ann McIntosh. When St. Michael's was closed in November 1863 because of the shelling of the city by Union batteries in Charleston harbor during the war. Elliott joined the Rev. Mr. Howe to minister to a refugee congregation in St. Paul's, Radcliffborough. He resigned his position at St. Michael's in December 1865 when his brother made him rector of the Church of the Advent in Madison and vicar of the Church of the Reedemer in Greensboro, Georgia. In his two years there, a new church was built by his nephew, Captain John G. Barnwell. Leaving Georgia in 1868, he became the editor of The Christian Witness in Boston and assisted at Trinity Church and at St. Paul's in Brook-line when their rector was in Europe. In October 1870 James became rector of St. Paul's, Radcliffborough, the parish of his boyhood. He narrowly missed being elected bishop of the diocese in 1871. As his father and brother before him, he was honored by Columbia University with an honorary degree (S.T.D.) in 1871. During a short but fruitful ministry at St. Paul's, he was a member of the Standing Committee (1872- 77), a trustee of the General Theological Seminary (1877), on the boards of examining chaplains and missions (1873 -- 77), twice (1874 and 1877) a delegate to the General Convention, and the unsuccessful leader of a move to prevent a separate jurisdiction for Negro parishes. He died suddenly June Ii, 1877 and was buried in the churchyard. The services at St. Paul's for the two Sundays after his death were taken by his nephews, the Rev. Stephen Elliott Barnwell and the Rev. William Habersham Barnwell, and the Memorial Sermon at his funeral was given by the Rev. C. C. Pinckney.
