This happened about 1787 about a mile from Clark's Blockhouse located between Big Wheeling Creek and Little Grave Creek: The only names I know of the Bevins family massacred at Graves Creek are three of the four children in the household:John (killed), daughter who was the wife of James Anderson, and Cornelius, the only survivor.
Four children are few for that era.Because one daughter was married I suspect that she had adult brothers who would have had households of their own elsewhere.
There may be records of the Bevans parents in the resolution their estate.See the following:
Exerpt from WV University, history of Marshall County:
Zackquill Morgan, son of Morgan Morgan, served in both the French and Indian War and in the American Revolutionary War, rising to the rank of Colonel. He received a legal certificate for 400 acres of land in the Morgantown area in 1781. In October 1785, at Colonel Morgan's request, the Virginia General Assembly specified that 50 acres of his land was to be laid out in lots of a half acre each, and a town, named Morgans-Town, established on the site. The lots were to auctioned off and the proceeds given to Colonel Morgan. Initially, the land deeds required purchasers to build a house of at least 18 square feet on the lot within four years, but because of Indian hostilities the four-year time limit was extended in 1789 by the Virginia General Assembly an additional five years.
Important Events in Monongalia County during the 1700s
Monongalia County government's first organizational meeting took place at Jonathan Coburn's home on December 8, 1776. His home was located about two miles east of present-day Morgantown. Captain John Dent was named the county's sheriff. Because the new county's population was concentrated in the county's northern portion, it was decided to hold the county court meetings at Theophilus Phillips' plantation, Phillips' Choice, a few miles from New Geneva, in present-day Springhill Township, Fayette County, Pennsylvania.
In 1782, after the extension of the Mason-Dixon line made his home a part of Pennsylvania, the county seat was moved south, first to Colonel John Evans' home and ultimately to Zackquill Morgan's home in present-day Morgantown. The county court was held in Morgan's home while a courthouse was constructed in the public square in what was then called Morgan's Town. The wooden court house was completed sometime between 1782 and 1785 at a cost of $250. It was at about this time (1784) that George Washington visited the area.
