I have started a research group on Facebook.
Nipp/Knapp-KIN and allied Families.https://www.facebook.com/groups/127550904084488/
This centers around the Nipps/Knipps/Nepp/Knepp, and all variations of that surname, but also includes the families that married into those lines. Coe, Coker, Covington, Luna, Looney, McCracken (to name a few).
it is my hope that many researchers working together and pooling resources can accomplish more than we can on our own.
