First, in checking the location where William Yates bought his land in 1776, we find that the head of Little River is located within ten miles of the Loudoun County line. In fact, Little River flows in a northwesterly direction from Fauquier into Loudoun County.
Further, we do not find the name of a William Yates in the records of Loudoun County, other than the mention in his father’s will. If William Yates was about 29 years old at the time of his first child’s birth in 1766, he would have been born about 1737. That is a reasonable birthdate for the William Yates, son of Joseph. William would then have been about 90 years old at the time of his death.
