Don't know about Rupe and not much about Waits; however, many Waits settled near Piedmont, MO and some of them are still there, others moved to St. Louis and no doubt elsewhere. Once while at a cemetery near Rockford and Fairfax, MO, I saw a couple of Waits names on tombstones. This would probably bew Atchison Co or near it. The man's name was, I believe, Ransom Waits.
My husband is Asa Lee Waits, III (A. Lee); his Dad was Asa Lee, Jr.; and his Dad was Asa Lee (sometimes spelled Asalee) Waits, III. His parents and grandparents are buried in the Piedmont Cemetery and there is even a Waits Road (or Waits Valley) still just outside Piedmont.
Good luck.
