Welcome to WikiTree, Rodney.
I did some googling and found some interesting items related to this topic:
* General background (but not updated with the info that follows): https://en.m.wikipedia.org/wiki/Creek_Freedmen
* https://apnews.com/article/muscogee-creek-tribe-freedmen-slaves-citizenship-c8b461db1b5d792654cf5620777fed7b
* But the Creek Nation is still resisting: https://www.axios.com/2024/01/15/creek-enslaved-people-freedmen-muscogee-creek
* FamilySearch's Wiki has a page for researching Creek genealogy: https://www.familysearch.org/en/wiki/Creek_Indians
Looks like a Category has been created here on WikiTree for Creek Nation Slavery:
*https://www.wikitree.com/wiki/Category:Creek_Nation%2C_Oklahoma%2C_Slavery
Lastly, WikiTree's Native Americans Project has two inactive teams/subprojects related to the Creek: the following should be merged:
* https://www.wikitree.com/wiki/Space:Muscogee_%28Creek%29
* https://www.wikitree.com/wiki/Project:Creek_Tribe
If this is an area of interest and knowledge to you, we look forward to your participation.
