In my admittedly limited time spent so far researching my Elkins line, I gather that the Patawomeck tribe was part of the Powhatan Nation. As I understand it, Chief Powhatan headed the Nation and had lesser chiefs (our Japassus and Wahanganoche) ruled their tribes. Similarly to feudal England where the King was overlord of the kingdom and the lords were overlord to the peasants who lived on their land. Japassus was father to Wahanganoche. I've also read that one of Powhatan's wives (it's said he had many) was from the Patawomeck tribe.
Bill Deyo, the tribe historian, should be able to answer any questions. His email is - firstname.lastname@example.org
