Family History Volumn

Jim,
What volumn do you suggest that I purchase first? There are so many and I would like to get 1 or 2 at a time. I can go back as far as George Ringo from Kentucky. His son was William H., and his son, James ALbert Major Ringo is my great grandfather who lived in Clay County, IN where I reside. Then there was Harvey William, James William (my father) and Timother James (my brother). Unfortunatly Tim is the last of our Ringo line because he has daughters and my dad was the only son. I don't know if Harvey's brothers have any grandsons.
