There is a Mary L Posey listed in the NAIL files as well as my Mary E but they don't tell you much, you have to send for the files. Then again I have a copy of the 1902 last call and there are alot of stricken from the roll places. so even if they're not there that doesn't mean anything alot of indians didn't regeister because they didn't want anyone to know they were indian back then. I did find looking at the rolls that the indians took everything from Irish to German names and when your doing your famil tree just because the name looks Irish etc. check it out it may not be, thats what makes it so hard to trace. Do you know where your family came from? I started working backwards, my grandfather, than his parents,then his grandparents sometimes you can find out things that way. My ggrandmother lived in ND but I'm fairly sure she was born in WI (no records of birth back then ).You can usually find out where they were born from the census of the last place you know they were sometimes your luck and get a good listing some states you don't. Anyway it goes this way so far Mary E Posey was born in WI (Marietta a civil town) her father was George Posey IL(Washington middle name ? ) mother was Abra Mongonery Huckions Kielley from OH the thing that I can't figure out is the indians combined tribes to protect themselves when the white man was forcing them to move and Creek indians as well as the other tribes are a mix of tribes. You maybe lucky and have someone in your family remember a little piece of something that can help you connect.If I have any information I'll send it. By the way there was another Mary Posey in ND in 1885 any possability it is connected to your ma?
