The Martin DNA Project is here: http://www.martindna.com/ The testing should be explained there. They use a cheek cell sample from a male by the surname of Martin (or which ever line you are researching). The Y-DNA is passed from father to son, to son, forever, so, your earliest Martin ancestor will have the exact same DNA as a living Martin male descendant. All males of the same line will have the same DNA so a match means that you are from the same line. Julia In a message dated 3/5/2005 11:18:20 P.M.
