Looks like several of your matches note that they are descended from Austin Odell/O'Dell etc.
Wow, that was a popular name among the O'Dell clan members! There are a lot of Austin and Augustine O'Dell profiles already on WikiTree.
You can run a search for Austin Odell; I got 18 hits.

Your mission, should you chose to accept it, is to get a handle on the Odell and Woodall families of your Y-DNA matches, and then you might see where your own line could fit in.
The phonetic similarity between Woodall and O'Dell is fascinating too. What if it turns out to be the same family?
