"The following is a sketch of the history of the ancestors of Abraham Armstrong, of Jefferson Township, as handed down orally or by tradition. His great-grandfather, Adam Armstrong, lived in Washington County, Pennsylvania, where he raised a large family. Some of his children moved to Greene County, Pennsylvania, in early times. His son Abraham, grandfather of the present Abraham Armstrong, was born on June 27, 1747, and married Florence McLean. They had fourteen children, including a daughter born to his wife by her first husband - seven sons and seven daughters - all of whom reached maturity. John, their eldest son, and father of Abraham Armstrong, was born May 6, 1781, and married Susannah Henderson, who was born in Mifflin County, Pennsylvania, May 20, 1788. They were married in 1809, and in the autumn of 1813 moved to the pleasant site occupied by the subject of this sketch. Their children according to age are Abraham, Amelia, John, Thomas, McLean, Elizabeth, Margaret, Alexander McCoy and Susannah Jane. The father died in 1852 and the mother in 1870. Abraham was born March 2, 1810, and succeeded his father in the milling and farming business. The grist-mill was first built in 1815 and was twice rebuilt. When six months old Mr. Armstrong lost the use of his right leg from sickness, and has used a crutch through life. Like many young men in this locality, he taught school during the winter season."
