Since prehistoric times Native Americans have migrated. This migration both voluntary and forced continued into the 20th century.
I have made and example of one of these to help every one working in the projects.
I have finished a project for each Region and state. I was working with my own state, MO and the first tribe on the list were the Caddo.
as you see, the Caddo are mentionrd in MO, but the main tribe will be found in TX so after a short note I put the link " See [http://www.geni.com/projects/Native-American-Tribes-State-of-Texas Texas] "
Now if you follow me to Texas you will find the Caddo Tribes listed (number 9) and you will see that I added "+ note in MO " . This will let the person that is working on the Caddo in Texas that there is something in the MO tribes about them. This is the only way that we can keep links up to date as the projects are worked on.
The link for MO is http://www.geni.com/projects/Native-American-Tribes-State-of-Missouri
Erica, true but if you think of it, if you do a tribe or nation, you can point all the states (or in some cases also to canada or mexico) to show the area.
You work with the Cherokee alot, and although most people only know of the two Cherokee Nations, as you know they are spread out over several states.
To the north we have Some Reservations that cross into Canada, and some tribes crossed over into Mexico. In the US alone 55.7 million acres (2.3%) of the US is Managed by Native Americans. The are only 310 Reservations but 550 recognized tribes. ( http://en.wikipedia.org/wiki/Indian_reservation )
That means 240 reconized tribes don't even have tribal lands.
Tracking them thru time and states (counties) is the only way I know that it can be done.
And into Mexico down here in Tucson! I think we should do reservations separately as Geni enhances and works with "Places," and do tribal projects for now. The division Marv made by Mountain, Southeast, etc. Makes sense to me as a frame for tribes. Sub divisions into bands does not seem warranted at least as yet.
Although I broke it down by stae.. in those cases were needed such as a Reservation that is both in the US and Canada (IE The Mohawk) it may be simple to simply create a project for it and link it both from the NY State project and the Ontario and Quebec Projects.
There's a lot that can be done, each state/tribe/reservation will have to be looked at, and someone from that region will have to decide what may be best.
As for places, I can show you lists of indian villiges, but normally you will only find one or two people connected to each villiage. That's not worh oppenig a project for.
