I claim descent from John d 1754 Pasquotank through his son Joseph ("Jos.", with raised s). The number 75 precedes the names of each subject person in the Pasquotank probate list, and is not an indication of John's age at death, although he may not have been far from 75.
The DNA of Biggses who trace their lines back to Joseph Biggs and John Biggs of the northeastern part of NC matches, and they are believed to be Joseph and John, sons of John d 1754. Surprisingly, their DNA does not match that of several descendants of James Biggs of Currituck Co NC, who has long been believed to have been a brother of Joseph of Martin County.
If direct male descendants of Rev. Davis Biggs of Pike Co MO would consent to be DNA-tested, I'm confident, as are other researchers, that they would match descendants of James of Currituck. If so, this would help convince researchers that the Robert, Davis and Imorish or Immoriah Biggs (however spelled) mentioned in the book "John Biggs, the Welshman..." are the Robert, Davis and Amariah Biggs mentioned as sons of James of Currituck in his will.
