Rose Mary,
Are you aware of any sources that would confirm that Quantrill personally knew or met or cooperated with Stand Watie, William P. Adair, or other Confederate Cherokee?

I've seen claims that Quantrill was in the Cherokee Nation before Wilson's Creek and accompanied a contingent of Cherokee to the battle. Union sources often put the two together -- Quantrill and Watie. However, I'm not aware of any credible documentation that puts to two together or indicates they cooperated.
