If I am understanding your correctly, you feel that your research was done carefully and are quite confident with your conclusions. I would agree just by looking at the number of sources you have already included. Then, you have discovered that other people have done similar trees that are in conflict with what you have done. How am I doing?
I have often found the same sort of thing on Ancestry, Family Search and the like. You can question your methods, but you know how you work already. Take a close look at these other trees and see if they make sense. Often, they do not. I have seen completely ridiculous conclusions, such as an American family of German descent, apparently traveling to England to have a daughter. Could it happen? Of course! But did it? Really? Nah.
Just double-check your conclusions to make sure you haven't confused two similar families. One clue is location. Sometimes families are missed on the census. In your family it appears that everyone was born in NC and then moved to Indiana. Families tended to stay put after a big move like this - or push forward and go further west. I would find it suspect if they moved back East.
What I am saying is, if you are confident in your research, go ahead and enter it on WikiTree. If a mistake is made, it can be fixed. We alter relationships, etc. all the time, if needed.
