The following, regarding Neil McCloy and his family, was extracted from the book, History of Washington County, Pennsylvania with Biographical Sketches of Many of Its Pioneers and Prominent Men (Boyd Crumrine, editor):
Neil McCloy was a native of Ireland, and a physician. He emigrated from Lancaster with two sons, of whom Alexander became a physician, and practiced in that county. He came to this country in 1835, purchased, October 19th of that year, eighty acres of John Bracken [see Thomas Bracken], part of the Robert Miller tract, which had been sold to Kerr, and in 1838, purchased one hundred and thirteen acres of land of Ebenezer McClelland, now owned by Nathaniel McKnight and John Hays. David D. McCloy was the only son of Alexander, by a first wife. Other children, by a second wife, emigrated West, except Samuel, who settled on the farm, where he lived till well advanced in life, and sold the farm and moved to Canonsburg, where he died.
