That info matches what I already have, with the exception of that I show the name being ANDREW L. Lewallen (as opposed to ANDERSON Lewallen) who lived 1793-1873, married Malinda Elizabeth Davis, and fought in the War of 1812. ANDERSON was the first name of the FATHER of Andrew L. and Sheriff John.
This is the same Andrew L. Lewallen I'd mentioned in my previous post as being a non-match for "my" Andrew Lewallen. Similarly, Andrew L. Lewallen's son, Andrew R. Lewallen, is also a non-match for "my" Andrew.
But I appreciate your reply very much, and hope to eventually find the parents/line of "my" Andrew Lewallen (b. 1829) and how he possibly connects to these other Lewallens.
Take care, and Happy New Year!
