The following, regarding William Craighead 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):
William Craighead, son of George Craighead of North Strabane township, came to Cecil in 1806, and on the 25th of April in that year purchased one hundred and eighty acres of Reed and Sally Bracken, heirs of Thomas Bracken, a part of the tract called "The Three Shares." His son George settled in Peters township. James and John, also sons, live on a farm adjoining Canonsburg. The homestead of William is now owned by William R. Craighead, son of George and grandson of William.
