This small borough was incorporated on January 9, 1893. Rockledge was formed due to an overflow of Philadelphians from Fox Chase, an old community just across the county line in Philadelphia. Its approximately four-tenths of a square mile were taken from Abington Township. Primarily residential in its land use, most of its residents work in Philadelphia or other portions of Montgomery County. It should be noted that some homes and businesses, while having a Rockledge mailing address, will actually be located in surrounding Abington Township.
