According to the 1878 survey of Anne Arundel County prepared by G. M. Hopkins, Civil Engineer (CE) of Philadelphia, the area that is located along the West Branch of the Patapsco River and is now known as Pumphrey was owned in large part by Charles Pumphrey.
Charles Pumphrey was a direct descendant of Walter Pumphrey. Walter was a Quaker who emigrated from England and arrived in Burlington, New Jersey, on a "boat load of Quakers" in 1678. Walter Pumphrey moved to the Baltimore area in 1708 to provide carpentry services to the many Quakers in that city. He purchased property throughout northern Anne Arundel County for a source of wood. A section of marshland in the area between what is now Linthicum and Pumphrey was known for some time as "Pumphrey's Swamp."
