James may have had other children (Robert?) who were gone from home by the time of the 1850 census report.
"In July 1814 James and brother Robert were listed in the sale bill for the estate of William Herring. James was first taxed in Harrison County in 1816; he continued to be taxed in Harrison County through 1828. However, in 1827, James Clifford, presumably our James, purchased land in Harrison County from James McKee, who had previously, in 1807, sold part of his land to William McKee, brother of James McKee. In 1835, James Clifford purchased land on Twin Creek, Harrison County, from George Stumph (Stump?). James was first named in the Harrison County federal census in 1820; he continued to be enumerated in Harrison County through 1860.
"James Clifford's estate inventory and sale bill was reported 10 January 1861. Robert Clifford, presumably his son, was Executor. Cliffords making purchases were John J. Clifford (son; his one purchase was the gun of his father's), R. Clifford (son Robert Clifford), B. Clifford (I can not place this B. Clifford; could he be Levi?), and Liza Clifford (daughter, Elizabeth). Most items of the $294 estate were purchased by son Robert (a major item being 1000 pounds of pork) and daughter Elizabeth (including most of the livestock). Other purchasers included John Farlaw, Samuel Beard, Ben Hume, A. Day (perhaps Alfred Day who was the administrator of Mary Chandler Clifford's estate), Mouse Ashbrook, R. King, William Terry, W. Berry, E. D. Cason, Guy Bryant and Charles Norton (husband of James's daughter Frances Clifford)."
