I had this
Linky in my bookmarks for reference... I kinda suspect that a lot of bows this guy talks about may have been kids bows as generally bows were reasonably well made but I haven't checked him out so wouldn't swear to it either way.

Just happened to notice that the author says the information comes from several books so I suspect I am right about the kids bow's.
The Southeastern tribes, Cherokee, Creek, and others made their bows out of several different woods depending on what was available in their particular area. When Mulberry is talked about being used for a bow wood a lot of folks make the mistake of thinking it was the sap wood that was used when in reality it is the heartwood, same as Osage Orange, Hedge apple, Hedge, Bois D' Arc, all the same tree.
Bows could run from 40 to 80 pounds draw. There's a Creek Osage Orange bow on display at Mohawk Park here in Tulsa that I'd estimate at about 60 # draw, I'd give my left pinkie for it, no questions asked.
In case anyone didn't check the link at the top of the page in the first website above this
Linky is the index page to the whole site.
I understand from some of my Lakota buds in So Dakota that it wasn't unknown for some of the old Lakota bow's to be well over 100 # draw and I don't have any reason to doubt it. It's gonna take a pretty heavy bow to sink even a 24" arrow up to the fletching in the side of a buffalo you're riding along side of on horseback!
