How can I get military lists of Eli Branic and who he served with during the Civil War?

How does Osage General Broke Arm fit into the Cherokee Volunteers?

Is there a list of Cherokee Partisans that Eli may be on?

Can anyone suggest books, diaries, love letters or other writings regarding the Cherokee Mounted Voluteers?

Could Elias Brannick, Eli's brother have been a Osage scout for the North?

Any ideas?

Our great great grandfather claimed Osage through Josephine Brannick, Elias' daughter who married Jacob Church Jackson. Her grandsons were known to have spoken the Osage language.

Thank you, Darrell
