“Among the early settlers in what is now Cross Creek township were members of the CRAWFORD family, whose earlier residence was in Maryland.OLIVER and THOMAS CRAWFORD were the eldest of two sons of MARGARET CRAWFORD, a widow, who lived at Kenick’s Gig, in that State.When these two but lads they were taken prisoners by Indians and carried into captivity, where they remained till OLIVER was twenty and THOMAS eighteen years of age, when they were brought back to their mother by an Indian trader.OLIVER married and moved out to the Monongahela to the Redstone settlement, where he raised a large family, who with himself finally moved to what was then called “Kayntuck.”
THOMAS married about the year 1770, and in the spring of 1774, with his wife and two children and his aged mother, removed to Cross Creek and settled on the Hays farm, near the Beech Knob school-house.Here he commenced an improvement, and took up some two hundred and fifty acres of land.About the year 1778 he lost his aged mother.She was buried under the old oak tree in the old graveyard at Cross Creek, and was the second person buried there.Soon after this he removed to another part of his land, where THOMAS ANDREW now resides.Here he lived until his death, which occurred in June, 1783.The land that he held at the time his death is still held by his descendants.William Perry, Esq., owned the spot where he died, his wife being a great-grandchild.He was also the grandfather of the venerable THOMAS MARSHALL, of Cross Creek township, and also of MRS. DR. CREIGH, of Washington, Pa. “
