How did Jericho, Pennsylvania get its name? This page provides a brief history about the naming of Jericho, Pennsylvania, the people who settled it, and the industry rising within it.
Hamlet in central northwestern Upper Makefield Township on the southeastern slope of Jericho Mountain. It was founded by Jerry Cooper. A correspondent suggests, “Who is going to start the yarn that the name Jericho is a corruption of Jerry Cooper?—Jerry Co (oper)! Unfortunately for this, he didn’t settle in Jericho until 1795. But that probably won’t stop somebody with a fertile imagination.” Jericho was known as Raylmans in the middle of the last century. The Morris Map of Bucks County, 1850, shows four families of Raylmans resident at or near Jericho.
Josiah B. Smith in his manuscript Journal, 1874, actually does give this explanation of the name. He says the original name of the mountain was Jerrico Hill and that Jerry Cooper lived on the hill at a place called Jerrico. Cooper was a Tory during the Revolution and fled from the county to avoid arrest. After the war he returned to Jerrico and resumed work at the carpenter’s trade.
