Going backwards, I've found a link between myself and Don Juan De Xavier through my great grandfather, Clarence Enoch Dayley. His mother was Annie Sever, whose father was Herman Severe (b. 1820). His father was James Severe (b. 1775) who was the son of Robert Severe (b. 1750, Virginia). Robert's father was William Severe (b. 1702, England), making Robert the grandson of Valentine "The Huguenot" Sevier (b. 1678, Navarre, France). But his mother was Catherine O'Neil, not Joanna Goad. So, where, if at all, does Gen. John Sevier fit into this tree? Was he Robert's half-brother?
