A tangent story is that of We-He-Sa-Ki (Hard Rope). https://www.kshs.org/publicat/history/2018spring_mccaffery.pdf

They without doubt knew each other. Both were driven to maintain Osage autonomy and independence. They ended up on opposite sides of the coin but may explain some of Mathews behavior around the Osage Mission. I suspect both were at Albert Pike's conference to try and get Indian support for the Confederacy. Mathews being a bit more of a direct action guy and less of a diplomat than Hard Rope. The article also spells out the split within the Osage tribe.
