Among his contributions to the war effort was the provision of supplies carried by Stanley's ships that allowed General George Washington’s men to survive winter at Valley Forge.
Stanley was later accused of counterfeit, and until he proved his innocence, he was placed in a debtors prison in Philadelphia. When Stanley died of yellow fever in 1789, he left behind nine children. His son, John Stanley Jr. occupied the home until the 1820s. In the Civil War, the home served as the headquarters of Union General Ambrose Burnside. The home was a convent after the Civil War. The home was used as a public library from 1935 to 1965 and then donated to the Tyron Place Commission who currently operates the house as a museum.
