* The main goal is to identify related families deriving from the Yarger families in eastern PA in the 18th century.

* DNA tests should allow us to separate lines that are not related and allow us to concentrate on related lines.

* Those results not closely releated to the primary objective family may identify other family clusters. These families are welcome to particpate and develop their own relationships until such time that they may wish to breakoff to form their own specific group.
