Isn't the text's introduction slightly glorifiyng? It tells the story of the noble settlers who had to fight troubles and sometimes even lost their lives - it leaves out that they actually have slayn all the indigenous people whose country they invaded. Colonialization of North America isn't just some exiting bunch of tales about adventurous pioneers, but actually a quite cruel story of suppression and murder. So maybe you should consider some other entry point for your text.
