I do not know the reason why Col. George Gibson's parents were removed. Col. George Gibson and his brother, Gen, John Gibson are sons of George Gibson (1704-1761) and Martha Elizabeth Devinez (orl De Vinez) (1710-1793).
It is practically a historical fact that his parents were George Gibson and Martha Devinez. Here are some sources: "Gibson's to America" by Sarah D. Gibson, 1910. Holy Trinity Lutheran Church records in Lancaster. PA. "Memoirs of John Bannister Gibson" by Roberts, 1890. History of Lancaster Co., PA "Narrative of Hugh Gibson" by Engle, 1887. George Gibson's Will written in 1761 where he mentions his wife, Martha, and all their children that include (Gen) John Gibson and (Col) George Gibson.
From the "History of York Co., PA", J. H. Beers & Co., 1907, pg 148:
Col. George Gibson, "a notable figure in the early military life of the country, who emigrated to America from County Derry, Ireland, early in the eighteenth century. In his younger manhood, Col. Gibson had been engaged in the trade to the West Indies, and afterward was a trader with the Indians at Fort Pitt. Returning to the East, he bought a farm and settled at Gibson's Rock, Perry County (then a part of Cumberland) and married Anna West, a descendant of the Wests of Ireland. During the Revolutionary War, he enlisted at Fort Pitt a company of 100 brave men, sharpshooters known as "Gibson's Lambs". He was commissioned colonel of the 1st Virginia Regiment, joined Washington before the evacuation of New York, and took part in may of the leading battles of the Revolution. In 1791, he took command of a regiment under Gen. St. Clair, in his campaign in Ohio against the Indians of the Northwest Territory. and lost his life at the Battle of Miami Village, dying at Fort Jefferson, Ohio, Dec. 14, 1791. He left three sons, of whom John Bannister Gibson became Chief Justice of the Supreme Court of Pennsylvania, occupying the bench from 1816 to 1831, and was one of the most distinguished jurists of the State."
