Passages that mention Bloomfield Township, cut from the printed page as they were published.
George Peiffer, about 1797, emigrated from Northumberland County and settled with his family in what is now Bloomfield Township. In 1810 he removed with his son George two miles below Saegertown and there remained till his death, which occurred about 1818. He built a large house soon after his arrival and kept tavern in it during the war of 1812 and for years afterward. A log schoolhouse stood near by and religious services were held therein by various denominations. This locality in early times was dubbed Peiffertown, though it contained no public buildings save what are mentioned above.
