mtDNA testing

To date, no known matrilineal (all female line) descendant of Sarah Allerton, wife of Degory Priest, has publicly revealed where they have mtDNA test results. In addition, the Silver Book Volume 8 (Degory Priest) only names a single matrilineal descendant of the Fifth Generation (#65 Abigail Richardson) and the book only lists were she had one son. There are a number of females whose further record (after their birth) is currently unknown, so it is still possible the matrilineal line may continue to the present day, but more contemporary "paper-trail" records need to be discovered to flesh out any potential matrilineal lines.
