It seems very long for young children to keep their attention. I can understand wanting to do a good history/story/account, but there is a lot of information for young minds.
There are things that I don't completely agree with, or feel that they could be related differently at least, the first one being.... Scotland isn't an island, part of one of course, but no one could find Scotland on an atlas by looking for an island!

I know that it must have taken a lot of work to get all this together, but with a bit of careful editing I'm sure it would go down very well.
