Updated 14 September 2024 The Big Y 700 is our test of choice for males. To help find family connections for the GRIFFITHs 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. The GRIFFI(TH,THS,N,S,NG...etc) surname project is intended to provide an avenue for connecting the many branches of Griffith, Griffiths, Griffin, Griffis, Griffing and other families with derivative surnames. The Welsh patronymic naming system, practiced into the latter 18th century, makes this task more difficult. Evan, Thomas, John, Rees, Owen, and many other common Welsh names may share common male ancestors. For results to be meaningful, participants will need to share their direct male line ancestry back to the earliest known GRIFFI... in the form of a pedigree chart, family group sheets, or preferably, an electronic GEDCOM file. Please exclude living persons from information you wish to make available on the project website.
