I may just be repeating information you already have, and this is not my line of Pettigrews, but as best I can figure there were three Pettigrew men in Orange County NC who were old enough to fight in the Revolution: John (Sr) (ca1752-ca1791), William (Sr) (<1757->1840), and Hance (Sr) (ca1758-ca1800)
John Pettigrew (Sr) was mentioned in a couple of deeds in Dec 1777 in Wake County, NC. In 1779 in Orange County, NC, John Pittigrew was taxed on a Property Assessment of 400 Pounds. In 1780 he was in St. Mary's District, Eno River Area of Orange Co (now Northern Durham Co). John Pettigrew had land next to a Willliam Pettigrew, indicating a brother (his SON William would have been too young to own land.) John has not been found on the 1783 or later taxes of this district and no record of his estate has been found, which might well indicate he left little property and no land. If his widow was in poverty, she would have had to apprentice out her children. Thus it is quite possible that Edie/Edy/Ede/Edi Pettigrew, born ca 1753, was John’s widow. Their children MIGHT have included Jane (born ca 1773?), James (ca1774->1860), John (ca1775-), William (an apprentice) (ca1781->1850), Thomas Grant (an apprentice born 1783-1884), Joseph (an apprentice born ca1785-), Nancy (an apprentice born ca1790-), and/or Abner (an apprentice born ca1791-1816).
William PETTIGREW (Sr) witnessed a deed for John Pettigrew in 1777. He appears on the 1779 and 1780 Orange County, NC Tax Lists and for the next several years is listed in St. Mary's District, Orange Co., NC. On 6 Aug 1785 William & “Hans” Pettigrew witnessed the Will of James Harris, Orange Co. NC. In Nov 1785 Hance Pettigrew and William Pettigrew proved the Will of James Harris, in Orange County Court. In 1790 he is on the Tax List, Orange County, St. Mary’s Dist as as Wm. Peddegwin. 28 May 1795: Bought 96 acres in Orange County on Granville County line. In 1797 he was taxed on 116 3/4 acres, the only Pettigrew in these taxes with land. 1798: 20 Acre Land Grant, Orange Co. 1800: Taxed Orange Co but not on census. 1810: Granville Co as Wm Petifrew Senr, age over 45. His children MIGHT have included William (Jr) (1779-1852), Hance (Jr) (1782-), Sura? (ca1785-), and/or Charles (ca1788-1846)
Hance PETTIGREW (Sr): On 5 Sep 1776 Ance Petigrew enlisted in Army, NC, 10th Regiment, Col. Abraham Shepard / Ballard's Company. 15 March 1781 Captured in Battle of Guilford Courthouse, NC. “Hans Pellegrew, from Orange County,” was paroled by Lord Cornwallis. 17 May 1781: Hans Pettigrew married Elizabeth Edge (Granville Co NC Marriage bond) Bondsman: Nathaniel Clark. (Granville Co NC Marriage Bonds). 1782 Ance (Hance) Pettigrew and William Pettigrew, of Hillsborough District, NC, signed a Petition in behalf of Thomas Hunt, who was under sentence of death for horse stealing. Taxed in St. Mary's District (Orange Co). 6 Aug 1785: William & “Hans” Pettigrew witnessed Will of James Harris, Orange Co. NC. Land Warrant No. 2022, dated 10 August 1785, granted to “Hance Pettigrew, a non com. offcr., wounded,” for 1,080 acres, for 84 (?) months service, “for Capt. Nickols, Hilsbro.” It appears Hance Pettigrew moved to Georgia about 1786-1789. Hance Pettigrew received a land grant of 175 acres in Hancock Co GA on 3 May 1790. 1793: Hance Pettegrew on tax list for Cambells District, Wilkes Co GA, for 100 acres. Hans co-administrator of the estate of Isaac Cook in Warren Co GA on 15 Jul 1797. Warren Co GA Fereby Cook and Hans Pettigrew apply for administration on estate of Isaac Cook, dec'd., July 15, 1797.] Hans witnessed a land deed of J. Harmon of Warren Co GA on 18 Jan 1798. May 1798: Some of Hans’s land was sold for back taxes. 1803: AN Elizabeth Pettigrew, who may or may not have been the widow of Hance, drew two draws in 1803 Land Lottery in Wilkes Co GA (implying one draw for herself and one for her children). Whether or not THIS Elizabeth was the widow of Hance, they may also have had other children because when Elizabeth Pettigrew had a draw in the 1806 Land lottery in Hancock Co., Georgia, the "orp. of 'Ham' Pettigrew" also had one draw.
Now we finally get to Hance PETTIGREW (Jr), who was probably born about 1782-1784, shortly after the marriage of his parents. On 28 Mar 1804: “A” Hance Pettigrew married Livinia Owens in Orange County NC (daughter of Only OWENS and Sarah LAYFIELD). [Did sisters marry cousins?] 1810: In Guilford Co: NC “H. Pittegrove” age 26-45, with family. 1811: Probably in Guilford Co NC where he inherited estate of Ephram Jenkins.
Also of note is Sura PETTIGREW – the only record I have found of her is her marriage bond:
Groom: Sion Parish
Bride: Sura Pettigrew
Bond_Date: 20 Aug 1805
Bond #: 000099685
