Updated 14 September 2024 The Big Y 700 is our test of choice for males. To help find family connections for the PRYORs of all spelling and variations. By joining the group you agree to provide the project with 3 things. 1) The surname of the person being tested. 2) The name, date and place of birth of the oldest researched male ancestor of your male patrilineal line and the oldest researched female ancestor of your matrilineal line. 3) Permission to publish the DNA results and the names, dates and places of birth of the oldest known patrilineal or matrilineal ancestor.. Which Pryors are related to which Priors? We can identify individuals related through our male ancestors. We can determine likely locations of our family origins. These objectives and more can be achieved by comparing the Y-DNA of males who share our surname or a variation. All males whose direct paternal male ancestors - father's father's father - may have used the Pryor/Prior/Prier surname (and its many variations) are welcome to join the group.
