Jeremiah Trexler obtained land adjoining that of his father in present-day Upper Macungie Township, where he operated a tavern as early as in 1732. Two years later, in 1734, a road was developed from his Upper Macungie Township tavern south through North Wales to Philadelphia.
As was the custom of the time, a village grew around the tavern, and the village came to be known as Trexlertown in honor of Trexler's role in its founding.[5]
According to the U.S. Census Bureau, Trexlertown has a total area of 2.1 square miles (5.4 km2), of which 0.02 square miles (0.04 km2), or 0.80%, are water.[7] Schaefer Run and Iron Run join in the southwestern part of the community to form Spring Creek, a southwestward-flowing tributary of Little Lehigh Creek and part of the Lehigh River watershed.
