Family Tree DNA (FTDNA) is the organization that does the testing and determines the results
Connection with WF is not required, but Terry helped start the Beasley project and is an excellent resource. Each of these websites have helpful tools.
Over the past year, my (Doug Beezley) genealogy work has been conducted with Ancestry and Family Tree Maker. I have begun to develop and expand existing genealogies associated with the DNA Project. These lines are located at Ancestry.com as Private, non-searchable trees. Anyone who can be placed in one of these trees is invited access.
