We would like to determine which Giffen/Giffin groups are genetically connected and closeness of the relationships Ultimately our goal is a global family tree that will connect all the various Giffen groups scattered around the world

I personally have corresponded with Giffen's in Australia, New Zealand, Canada, South Africa, Scotland, Ireland, England and the United States and we are now actively seeking direct male lineal descendants willing to have their DNA tested at Family Tree DNA
