Philip Barnhart and his brother Henry served in the Revolutionary War. Philip served two enllistments and was drafted for a third service, but hired a substitute. He was at the Battles of Germantown, Bradywine, and Valley Forge. According to the notes of George Stackpole of Lewistown, PA, General Washington's army encamped upon the Barnhart farm during one of his campaigns, and the soldiers burned and destroyed the fences. Complaint was made to General Washington who mounted his horse and rose around the encampment and stopped the destruction. Philip's wife, Elizabeth Antes, took care of wounded soldiers in one of the forts during several battles. One the 6th of April, 1833, the legislature of PA passed an act granting relief to sundry soldiers of the Revolutionary War and from the provisions of that act it is learned that "The state treasurer is authorized and required to pay Philip Barnhart and Lawrence Bathurst of Boggs Township, Centre Co., Pa., solders of the Revolution, or to their respective orders, forty dollars to each immediately and an annuity of forty dollars to each during life, payable semi-annually, and to commence on the first day of Jan, 1833." Philip Barnhart and family settled in Northumberland County and settled on Nippenose Creek, not far from the home of Col. Antes, his wife Elizabeth's father. He then followed his trade of weaving. In 1806 the family moved to Centre County and settled in Boggs township. Philip Barnhart was one of the original members of the old Bald Eagle Valley Chapel Church. He was a very devout Christian and was a class leader of the church for more than twenty-six years. He died in April, 1843, and his wife died August 1845. They were buried at the old Eagle Chapel Graveyard, but later were removed to the new cemetery on the Sand Hill.
