Benjamin Parry was a third generation Quaker, born on March 1, 1757. He came to New Hope, then Coryells Ferry, in the early 1780s from Upper Moreland Township when it was part of Philadelphia. He purchased the Hope Flour Mill from the Todd family after Dr. Todds death in 1785. The Bucks County Playhouse now occupies that site. Parry expanded the mill operations along the river, adding a lumber mill, saw mill and flaxseed oil mill. When the Hope Flour Mill was destroyed by fire in 1790 Benjamin Parry rebuilt it within a year and named it the New Hope Flour Mill, thus giving Coryells Ferry its new name. New Hope Borough was incorporated in 1837.
Benjamin completed the construction of the Parry Mansion in 1787, the year of his marriage to Jane Paxson.
