Ancestry in Robeson County

One thing that has caught my particular interest would have to be Ancestry in Robeson County.  From looking at the results a majority of people that are born and raised in Robeson County are mainly American Indian Tribes.  A primary example of American Indians would have to be the Lumbee Indians.  With a percentage of 28 they are considered as the majority within this part of the US when compared to others.  This is truly surprising and with that being said I hope to discover more about this some time in the near future.
