Read up on Lawson. He documented the Saponi and the Catawba in NC in the ealry 1700's. Both in Abbotts Creek Rowan NC (today Davidson County NC) and in Hawfields which was orange county. today would be that part of Orange County NC that became Almance County NC
I know people in the area of mid NC that are comming up with Indian DNA. many who Paul Heinegg has listed as African mixed are the people who were called melungeon or Redbone. These people do come up African and European on DNA. I dont know what the actual Lumbee tribe DNA looks like or if its published or public.
