The Indians who first inhabited this area were the Lenni Lenape Indians (meaning the “original people”). The Tribe in this immediate area was the Minsi or Wolf tribe. They were known to be quite warlike at times. These Indians later became known as the Delawares. This name was given to them by a white man, Lorde de la Ware. Indian inhabitants in the Sinking Spring area supposedly called the main spring as the sunken spring. White settlers later called it the “sinking spring.”
Penn Avenue is the main thoroughfare of Sinking Spring. There is a stone monument in the 3800 block of Penn Avenue. It was placed to identify “The Spring,” which is said to periodically appear and disappear. The Township of Sinking Spring has a large number of underground streams that carve out limestone and form sinkholes; thus the name Sinking Spring.
