Johannes Handwerk, Sr., was a large land owner. On November 27, 1761, he sold a tract of 400 acres of land, located in Heidelberg township, Northampton (now Lehigh) county, to his son, John Handwerk, and Nicholas Handwerk, Jr., for the consideration of 300 pounds. Of this tract 130 acres were taken up by warrant from the Province by Henry Hauser, bearing date of April 25, 1744. The 400 acre tract was bounded by lands of Michael Ohl, Peter Handwerk, Bernhard Neff and John Hunsicker. On October 26, 1786, three years before he died, Johannes Handwerk sold three more tracts to his son, John Handwerk.
