How did Edge Hill in Pennsylvania get it’s name? This page provides a brief history about Edge Hill in Pennsylvania, the people who settled on it, and the industry rising around it.
The first extended chain of hills of importance above tidewater, northwest of the coastal plain area, stretching entirely across the county from the river Delaware to the Montgomery line and passing through the lower part of Lower Makefleld, Middletown and Northampton Townships and the central part of old Southampton Township. The rocks of this ridge are of metamorphic formation of considerable economic importance, producing a well-known micaceous building stone, and a flat schist, also for building purposes, but chiefly for flagging, being known locally as “milkhouse stone.” Quarries have been opened in this ridge at Rocksville, Trevose, Langhorne, Neshaminy Falls and Morrisville. At Morrisville the formation dips under the river. The ridge’s highest elevation is soo feet at Langhorne. Edge Hill is also the name of a hamlet on this ridge in the extreme southwest corner of Lower Makefield.
