There is an Creek tribe in Atmore and they have a web page and you can contact
www.poarchcreekindians.org them but without you knowing what her indian name was I don't know how much help they would be able to get you. That being said if your great great grandmother was married in AL you might be able to find a record of the marriage license using your the grooms name at
http://www.rootsweb.com/~usgenweb/al...bia/vitals.htm. There are also census websites where you can search for family names. I found my great great great grandfather and children listed there. It is a place to start
Good Luck in your search
