About Us

Welcome to the GRIFFITH(S)-GRIFFIN-GRIFFIS-GRIFFING-etc Surname Project!

The Griffi(th)(s)(n)(ng) surname project is intended to provide an avenue for connecting the many branches of Griffith, Griffin, Griffis, and other forms of the surname. The patronymic naming system, practiced in Wales into the latter 18th century, makes this task more difficult. Evan, Thomas, Johns, Jones, Rees, Owen, and many other common Welsh names may share common male ancestors. Surnames included in the project include: Griffen, Griffeth, Griffeths, Griffets, Griffett, Griffin, Griffing, Griffis, Griffit, Griffith, Griffiths, Griffitth, etc.

For the results to be meaningful, participants will need to share their direct male line ancestry back to the earliest known GRIFFITH/GRIFFIN/GRIFFIS/etc., either in the form of a pedigree chart, family group sheets, or electronic GEDCOM files. Living persons should be excluded from the documentation.

Our surname project is registered at Family Tree DNA (FTDNA). Most of your questions concerning DNA testing for genealogy purposes can be answered at that site or by contacting me. Click here for the order form to join the Griffi(th)(s)(n)(ng) surname project.

A Celtic Heritage

The genetic history of Great Britain is currently being mapped and reveals that a significant percentage of Irish and Welsh males are R1b haplotype and may descend from Mesolithic Celtic tribes that repopulated Britannia after the last Ice Age.
