During the American Revolutionary War, while Major (later Lieutenant Colonel) Prevost was fighting for the British in Georgia and South Carolina, the women and children were left alone in Ho-Ho-Kus.

[6] In July 1778, word reached Theodosia that George Washington and his troops would be passing through Ho-Ho-Kus on their way from the recent battle at Monmouth Courthouse to White Plains in Westchester County, New York.

When the General and his entourage stopped at a local house, Theodosia sent an invitation to Washington for him and his men to come and stay at The Hermitage.

[citation needed] Visitors to the house during the Revolution included James Monroe, William Paterson, the Marquis de Lafayette, Alexander Hamilton, Lord Stirling and Aaron Burr.

[8] The large house consisted of wood-shingled roofs and pointed gables, allowing the classical music that played to be enjoyed along with the beautiful architecture.
