John Diefenderfer, the eldest son, was born in Macungie Township, Jan 25,1754- In 1784 he purchased a tract of 200 acres along the Lehigh River, then a part of Salisbury township, on which he was assessed in that township in 1785. It later became a part of Northampton township and is now included within the limits of the city of Allentown, where, in recent years, the Allentown Iron Company's furnaces were located. On this tract was a one and a half story log house, with a long, slating roof, over which towered a large black walnut tree, where the family resided. A large spring bubbled out of the ground and flowed into the Lehigh, which was destroyed after the building of the dam. "Deifenderfer's Spring" was a famous picnic ground and many political meetings were held there prior to 1830. John Diefenderfer was an active member of Zion Reformed church at Allentown, and at his death, March 27, 1815, was buried in the old graveyard at Tenth and Linden Streets. He married, Feb. 6, 1781, in Macungie Township, Charlotte Elizabeth Shankweiler, who was born March 25, 1759, and died June 27, 1821. She was the daughter of Jacob and Anna Louisa Shankweiler. They had six children.
