I think that you and I maybe "talked" 2-3 years ago about possible Lewallen/Lawson connections. My Matthew married Sarah Lawson. I understand your frustration with understanding the DNA results. I don't understand all of it, but Billie & Carol on the Lewallen website have been really helpful in explaining some of it to me. I guess I'm wondering if your Andrew and my Matthew are related since they so far on paper don't connect with any of the other Lewallens, were born less than 10 years apart, lived in the same area, and both married Lawsons. If you test with Family Tree DNA, they compare your results with everyone in their database and you have access to another larger database. I have a theory that my ancestor's mother was an unmarried Lewallen woman but I can't prove it at this point. So, like you, I will keep on searching. Good luck!
