Jeremiah Trexler obtained land adjoining that of his father in Upper Macungie Township, where he kept a tavern as early as in 1732. In 1734 a road was laid out from his tavern through North Wales in now Montgomery County to Philadelphia. As was the custom of the time, a village grew around the tavern, which came to be known as Trexlertown.
One of the four Yocco's Hot Dogs restaurants, the Lehigh Valley-based fast food establishment known nationally for their hot dogs and cheesesteaks, is located in Trexlertown at 7150 Hamilton Boulevard.
