In 1782, Conrad Worman emigrated from Montgomery County into Northampton (now Lehigh) County and bought the property which included the Crystal Spring, one of the sources from which the city of Allentown receives its water supply. He erected a house near this spring and this was afterward owned by his son, Abraham. He had eight children. He was born in 1745, and died at Allentown, Feb 1, 1818.
