Nothing is known about William Sterrett (or Sterritt) of Point Pleasant, Mason County, Virginia (now West Virginia). George C[orbin] Washington was a great-nephew of the president. He was born in Virginia, but had a plantation in Maryland and served as a U.S. Representative from that state. Lawrence Lewis was the husband of Nelly Custis, a granddaughter of Martha Washington who had been raised at Mount Vernon by President and Mrs. Washington. George Washington Spotswood was another Washington family member (probably another great-nephew of the president and cousin to George Corbin Washington).
