Sometime ago i read a book written by Greek traveller before 100AD, who navigated from red sea of Egypt to southern ocean or what we call today Indian ocean. The Greek explorer wrote extensively about people of the Horn, He divided them three major groups From Port Said in Sudan to Eritrea, Tigray, Gondor to Bet Amhara or modern Wallo he called Jabarti country, from Shewa to northern Hararge he called Orgoba country, from Aduluse to Harar including lowland of Afar, Somali and Oromo country he called that big chank: Harla country.
I think we have to look all directions, certainly the old tribes dead out secretly and slowly and new ones fill the vacuum without giving any credit to vanishing ones?
