You've got it. Phillips-Lee-Monroe make up the TriCounty Genealogical Society for that area of Arkansas. They are the ones who truly "p" me off but I keep going and going (Energize me!) and have found all my relatives that I originally knew were there.
Also, our friend Richard Schaeffer helped tremendously (GO RICHARD!!!) by looking up Draft Registration cards. You're be surprised at who you'll find in those counties that are not indexed but truly living in the areas.
Good luck and GOD bless!
