I have done a limited ammount of research on your Bittle family. If your Roy L Bittle came from the Atherton, Mo area he was most likely one of David Bittle's grandson's or great grandson's. All of the Bittle's from the Atherton - Sibley area all descended through David Bittle and Sarah(Huntsucker) Bittle. David Bittle was from Washington County, Virginia. He and several allied families migrated to Missouri sometime between 1816 and 1820. I don't have a great deal of information on this family. I have emailed a couple of people who have been researching the Jackson County, Missouri Bittle's for several years. As I hear from them I will ask them to respond to your query on genforum.
