The Bolton Mansion cemetery, as you can see from the plaque, was the John Rowland and Priscilla Rowland Sheppard (wife) burial ground. John and Priscilla were with William Penn on the ship, "Welcome" in 1682. Originally, there were graves here from Pennsbury Manor but those graves have been moved to the location of William Penn's home by the Delaware River. You can see that some of the grave stones can be still be read and some have been wiped away over time. If you visit the cemetery (towards the top of the hill on the Levittown Parkway), please realize that this is our history. These are the people who left England to set up a new life in a strange land.
