Do you have a link to the Mormon site, or what it’s called so I can google it? I really would like to know which Stewart clan I belonged to. On my mother’s maternal side they were Jones. Not sure if that is English or Irish. On my mother’s paternal side......yep, Indian. Not Cherokee though (ha). My great grandfather was full Creek. The only thing I got from him was straight black hair. The rest of me is pure Scots-Irish or whatever.
I then started to search in google until I found it...If most of your ancestors are American Indian, you probably won't find much there...On my mothers side it was Irish, went back far enough to also find Scot blood. The branches of the tree get more numerous the farther back you go....like 2 parents, 4 grandparents 8 great grandparents etc....I was only able to follow one branch back to the 1700's....some list date of birth and death, a few marriage etc... good luck...it was fun....
They also have a new beta site that is helpful:
http://pilot.familysearch.org/
This site is helpful for their forums which you can sort by state, county, etc.
http://genforum.genealogy.com/
And finally, this site is great for scans of actual documents from the Civil War, Revolutionary War, etc. They are a subscription site but they often have free access to groups of documents for a couple of weeks at a time.
