Proprietary House Historic Site Overview

Completed in 1764 as a residence for the colony’s Royal Governor, its 250 year history is filled with political intrigue, divided loyalties and family tragedy.

Over the years, the Proprietary House has served as a residence to New Jersey's last Royal Governor, a stylish hotel, a private mansion, a retirement home, a boarding house and now as office space and a museum. Yet one of its most telling periods is when it served as the residence of New Jersey’s Royal Governor William Franklin, illegitimate son of Benjamin Franklin. As Governor, he ran lotteries to fund roads and bridges, introduced an assistance program for farmers and helped found Queens College, now Rutgers University. His loyalist leanings caused a rift between him and his father that was never reconciled.

Proprietary House is owned by the State of New Jersey and the museum is operated by the non-profit Proprietary House Association. For more details and program information visit
