He was married.
"A wife was not mentioned in James's will, written 6 June 1780; but no females were mentioned in his will, and we know he had living daughters at that time. There is this puzzling statement in the Hunterdon Historical Newsletter (New Jersey), Fall 1977, page 6:40 "John Clifford [son of James Clifford] was a twenty-seven year old bachelor managing his widowed mother's farm in Bethlehem Township, Hunterdon County, at the start of the Revolutionary War [1776]." But we know that James was still living in 1780, when he wrote his will.
"Most of the Clifford information of that time, at least in 1700-1782 Hunterdon County, has to do with James's brother George. There are few documents pertaining to James Clifford. Assuming James's son Charles was born in Hunterdon County, New Jersey, in 1730, one would expect some early records of James in that county, as we have for George. Did James not live in Hunterdon County for most of this time? I know of no documents mentioning his occupation; presumably he was a farmer.
"I can find no records of James Clifford in New Jersey prior to 1755, when he and apparently his sons George, Charles, James, and Edward were on the Subscribers list, Connecticut land claims in western New Jersey. Our James could have been the James Clifford whose ear mark was recorded in Bethlehem Township (Town meeting Records) in 1771. He was probably the James Clifford mentioned in the accounting and order books of the Grandin Fulling Mill (present-day Clinton Township, Hunterdon County), 7 April 1776 and 9 May 1777; also mentioned were George Clifford (probably #10), 16 November 1781; and Edward Clifford (#13), 8 May 1779 and 14 March 1782.42 In 1778, James's sons George, Edward, and John were taxed in Bethlehem Township, Hunterdon County, but not their father, James.
"James, in his will, did not leave anything to his son Charles. This at first seems odd, but, as pointed out by Charles D. Clifford, James's will was made in 1780, at which time Charles had been in captivity for over a year. Probably no one knew whether Charles was even alive. James did remember son Charles, indirectly, in his will."
