I think you struck gold! Yes, Woodrow is a brother to John W., these brothers are 2nd cousins to my father. I have his line back an additional five generations. Their father was Benjamin Franklin McGlothlin (Ben), son of Henry Lewis McGlothlin, etc. You can view the entire family history I've documented on-line at http://worldconnect.rootsweb.com/cgi-bin/igm.cgi?db=wwaynemc...
If you have documented descendants for John W. I'd like to add those to my database as well.
