Built by George Ashton, a prominent member of St. Peter's Church,
General Warren Inn was owned by the Penn family at the time of the
American Revolution. Operated by Peter Mather as the Admiral Warren
during the Revolution, the tavern gave Warren Avenue its name. Mather, a
Tory, was credited with informing the British of the position of General
Anthony Wayne's troops before the Paoli Massacre in September 1777.
