He was the oldest son of William and Jane Patton Henry, who emigrated to America in 1783 and settled near Havre de Grace, MD. In 1794, the family moved to Peter's Creek, Washington Co., PA and were there during the Whiskey Isurrection, but took no part in it. In 1795, William and his brother Thomas, then fourteen years old, settled in what was later Beaver County and now Wayne Township, Lawrence County, making a small clearing and building a cabin.
