The best people to contact on that question is the Citizenship Department of the Muscogee (Creek) Nation in Okmulgee, Oklahoma. Citizenship in the Creek Nation is determined by its laws and constitution. The opinion of one of us on the Creek-SE message board is of no consequence. Just being of Creek heritage does not mean that you are automatically a citizen of a federal recognized tribe, like the MCN. Most state-recognized Creek tribes will accept authenticated Creeks as members, but there are many more requirements for a tribe recognized by the Bureau of Indian Affairs. For example, I probably have a lot more Creek ancestry than many Muscogee-Creek citizens, but as far as I can tell, I could never be a Creek citizen myself, because I am not a direct descendant of a name on the Dawes Rolls. Good luck! Richard T.
