The following, regarding Stephen Richards, was extracted from the book, History of Washington County, Pennsylvania with Biographical Sketches of Many of Its Pioneers and Prominent Men (Boyd Crumrine, editor):
Stephen Richards was one who took up lands under a Virginia certificate. It was surveyed to him as "Montgomery," and contained three hundred and forty-three acres, adjoining Thomas Faucett (whose land was in Allegheny County), Robert Hill, and Alexander Fowler. Hugh H. Breckenridge, as trustee, sold one hundred and ninety-one acres of the tract to Daniel Smith on the 22nd of August, 1791. He sold the same property to Thomas Dunlap on the 26th of September, 1805. Dunlap emigrated from County Down, Ireland, with three sons, Thomas, James, and Alexander, and two daughters. James was the only one of the family who married. He settled on the homestead and had three children, John, Elizabeth, and Nancy. Elizabeth became the wife of Joseph Work and settled in Texas. Nancy married John B. Weaver and settled in North Strabane. John, the only son, settled on the homestead, where he still resides.
