Editing Clifton Heights, Pennsylvania (section)

==History==
The demographics of the greater [[Delaware Valley]] were significantly impacted by European colonization. By 1754, Native American populations in this region had been significantly displaced, however various uprisings of Native Americans were common throughout the region.<ref>{{Cite web |title=Native American-Pennsylvania Relations, 1754-89 |url=https://philadelphiaencyclopedia.org/essays/native-american-pennsylvania-relations-1754-89-2/ |access-date=2024-04-22 |website=Encyclopedia of Greater Philadelphia |language=en-US}}</ref>

According to historian Freas B. Snyder, settlers set up a large tin kettle at a high point on what is now Oak Avenue, between Baltimore Avenue and Springfield Road. When hostile Indians were moving through the area, an alert would be sounded by banging on the tin kettle. This high point was called "Tin Kettle Hill" and would become a landmark used in three-point calculation [[surveying]], along with a point in Central Philadelphia and a point on the Delaware River to the south.<ref>{{Cite web |title=About |url=https://www.cliftonheightspa.gov/about/ |access-date=2024-04-22 |website=Clifton Heights, PA |language=en-US}}</ref>

The high point, Tin Kettle Hill, is believed to be the origin of "Heights" in the borough's name.

In 1839, Thomas Kent settled in the area and established the J. and T. Kent Company, which manufactured carpet yarn. The company's workers built houses throughout Clifton Heights, surrounding the Kent Mills factory. The original factory building and many of the millworker houses still exist today.
