Whoever this is she is not Paul Lamar Jr's daughter. He only had one and that is me.
NN usually means "No Name." The person probably didn't know your name. :)
I just looked. It shows someone added a step-mother for you and a child between your father and the step-mother? Are you able to delete it?
I removed her and send Pamela a collaborate request.
This person was taken from an ancestry.com public member tree. It was marked as living and was for that reason not shown with a first name.
