I think we should treat this website with caution. The author's purpose seems to be to find names containing the combination RA and then claim a reference to the Egyptian sun god. He also has a thing about volcanoes. Whatever the meaning of the Manding clan name Traore (also spelt Tarawiri) I'll bet my life that it has no relation to the Maori name of a volcano in New Zealand. As soon say that my name, Young, proves that I am Chinese. With regard to the surname Asare, Ghanaian surnames for which I've found an explanation have always turned out to be male given names. So I think there's a good chance that it's a patronymic.
