After completing his term in government, at age seventy-six Gibson and his wife Ann returned to private life, briefly remaining in Vincennes. He returned to live with his daughter and son-in-law, George Wallace, in Braddock's Field near Pittsburg, where he died on April 10, 1822, at age eighty-two, having suffered two years from an "incurable cataract".[24] Gibson County, Indiana, was named in his honor.[23]
