There are a number of tri-racial groups. The Ramapos are one of them. There are some in NC who are not Melungeons and there are some out of Louisiana. Heather Locklear is a descendent of the NC group and I have read that Steve Martin is a descendent of the LA group. I forget their names. Apparently Locklear is a common name in her group and she has publicly said that she is a descendent.
Is the NC group you mentioned the Lumbees? They are prevalent in Robeson County, where the county seat is called Lumberton. The Lumbees have tried in vain to be recognized as an Indian tribe.
"There are some in NC who are not Melungeons and there are some out of Louisiana. Heather Locklear is a descendent of the NC group"
Locklear is a Lumbee indian name. There are also the Redbones and the Brass Ankles.
The ones out of Louisiana are locally known as "Redbones."
