I goggled Easton and Hays, and found a family tree for Thomas Easton (1725-1793) and his wife Sarah Whitlock (1728-1793) of Albemarle County, VA. Here is a strange coincidence, after William Easton Hays' birth in 1819 in Robertson County, TN, his father William Hays, in 1822, moved the family to newly created Henry County,TN, where through a series of TN land grants, they settled in the WHITLOCK community. I don't know where it got its name. I've run into these coincidences before, so I don't get my hopes too high, but it makes me wonder. I think I have seen some Eastons/Eastins that had settled in Robertson County ca 1805 at around the same time William Hays arrived from VA. Do you know if any of the Eastons moved to TN ca 1800?
