My wife's genealogy is through the Hood family. The Kornegay's are cousins to us. I do not know very much about the Kornegay family, but have found some sources you might be interested in. Here they are:
Revolutionary War Records Duplin and Sampson Counties, NC By Virginia L. Bizzell & Oscar M. Bizzell
KORNEGAY (Kornegay), George, Sergeant, N. C. Militia Soldier of Duplin County, N.C., served as a sergeant under Capt. Wm Taylor and Col. James Kenan at the battle of Moore's Creek Bridge. For his 20 days service he received 4 pounds. In N.C. Army Accounts, vol. V, Bk 180 is voucher # 253 M for 2/12/3 pounds and in Bk 179 is voucher # 57 M for material aid to the militia of 1250 pounds. (This may have been from his father). George Jr. married Mrs Margaret Downing Lullum, a widow by whom he had six children. In the 1790 Federal census for Duplin county, George is listed in a family of six persons with 12 slaves. Margaret died around 1800 and in 1802 he married the widow Mrs Mourning Wiggins, who had a daughter Elizabeth, who later married one of George's sons. George and Margaret's six children were: 1- Civil who married 2 Aug 1783 to her cousin, John Kornegay. 2- Daniel who married Edna Flowers. 3- David who married Zilphia Oliver. 4- Basil who married Tabitha King (sister of the vice president). 5- Jacob II who married his step-sister Elizabeth Wiggins. And 6- George III. George Jr died about 1808 probably in Wayne County. He owned land in many of the surrounding counties and is probably buried at the "Kornegay old Burial Ground" on Kornegay land at Kornegay's Bridge on the Northeast Cape Fear River in Duplin County.
KORNEGAY (Kernagy), Jacob, Sergeant to Captain, N. C. Militia Soldier served as a sergeant under Capt. Wm Taylor and Col. James Kenan at the battle of Moore's Creek Bridge. He was paid four pounds for his service of 20 days. In N.C. Army Accounts, Vol. V, Bk 180 is voucher # 254 M for 1/12/6 pounds, voucher # 314 M for 11/9/8 pounds, voucher # 356 M for 8/7/9 pounds, voucher * 228 M for 4/5/6 pounds, voucher * 1015 M for 2/5/6 pounds and voucher * 220 is for a pay roll. Also in the army accounts in vol. v, Bk 179 are two vouchers showing Material Aid to the militia voucher * 56 M for 1250 pounds and * 177 M for 200 pounds. At the taking of the 1790 Federal Census, Jacob was listed in Duplin County as a member of a family of nine persons with 19 slaves. He was born about 1735 in Craven County, N.C. and was the son of George, the only member of this Palatine family not killed in 1711 by the Tuscaroras, and Mary, the lst wife. Jacob married lst to Elizabeth Fontaine who died before 1777 in Duplin county, and 2nd to Mary Ward. One child was named Martin (A Martin Kornegay married 20 Feb 1806 in Duplin county to Patsey Turnage). The soldier died in 1824 in Duplin county. Note: Anne Sivil Kornegay born about 1760 in Duplin County and died before 1806 is believed to be his daughter but needs proof. L: most monies listed in pounds/shillings/pence.
