The Legacy of John Clay: A Musketeer in the King's Service Protecting King James's Claims for Large Parts of North America for England and The Immigrant Ancestor of Numerous Clay Families in America by Baker (Bob) Clay
This genealogical book is mostly concerned with the life of John Clay around Jamestown, Virginia, in the 17th Century, but then changes its focus to his descendants, including Cassius Clay of Madison County, Kentucky, and the Clay families that gather in Beckley, West Virginia, for family reunions.
