The Howell Living History Farm, also known as the Joseph Phillips Farm, is a 130-acre (53 ha) living open-air museum located north of Titusville in the Pleasant Valley section of Hopewell Township in Mercer County, New Jersey.

[5] The farm was first created by Joseph Phillips, a blacksmith, who purchased 125 acres (51 ha) from William Bryant in 1732.

Henry served as a captain in the Hunterdon County Regiment of the Continental Army during the American Revolution.

An inventory of the farm on his death in 1805 listed two teams of oxen, two slaves, a Rockingham colt, and the flax in the ground.

[3] The final private owner of the farm was the Howell family, who donated the land to Mercer County in 1974 for use as a museum.
