William Ewing emigrated from Ireland some time before the national struggle for independence, and settled on the Connautcacheuge Creek in Franklin County, Pennsylvania. He was a native of Ireland, a grenadier, or member of the king's bodyguard. This guard consisted of a company of men, every one of whom was distinguished for his great stature. … His wife's maiden name was Eleanor Thompson. Their marriage must have occurred as early as 1759 or 1760, for we have record that their third child, John, died on January 27th, 1842, at the age of seventy-seven years. They were the parents of six children, viz.: Adam, Isabella, John, James, Robert, and Alexander.
