I found a will abstract for Joseph Hamilton d. 1818 who mentions sons: James, John, and William and wife Martha. Executors: Archibald Hamilton and William Pickett. Witnesses: Robert Gradson and Samuel McAddams. This is probably the Joseph Hamilton who married Martha Whiteside (or Whitsett) in Orange Co., NC in 1781 (bondsman: William Bradford).
Also the will of William Hamilton d. 1791 in Orange Co., NC who mentions son: Joseph and daughters: Nancy, Margaret, Elizabeth, and Jean. Nancy m. Thomas Bird. Margaret m. McCulloch? Elizabeth m. Peter Walker. William Hamilton's executors are his son Joseph and Thomas Bradford. Witnesses are William and Thomas Bradford.
Also the will of Archibald Hamilton, dated 1787, unfinished which mentions first son: Joseph and nephew: Joseph.
William, Archibald, and Joseph Hamilton are in Orange Co., NC as early as 1779 on the tax list.
Does anyone know more about these Hamiltons? Thank you.
