It looks like a Guilford point. It's a Middle Archaic point which makes it between 5000 to 6500 years old. As for what "Tribe" made it ... well ... that's a whole other story. I won't go into detail, but no one knows by what name early "tribes" called themselves. What you are thinking of is 'Indian', and Native Americans weren't 'Indians' as we think of them in Frontier America. So, in other words it wasn't made by a Pawnee, Shawnee, Cherokee, Iroquois, or Crow. Those 'tribes' didn't exist. When you think 'North American Indian' you are thinking of teepees and horses. 'Native Americans' are a totally different culture of people than what you are thinking, and Native American's made the point your daughter found. That's why a lot of 'true' collectors call them Native American Relics or Native American Artifacts, because Indian Arrowheads is kind of a cliche.
Sorry for the long version, but it needed to be explained.
