Thank your brother James Dahl. You seem to be very educated when it comes to the history, culture and archeology of the Horn of Africa. This is the type of replies and opinions you would hear only from an educated person. Once again thank you.The most convincing case is made by the Karanle Hawiye, which lines up with the little we know of Ahmed Gurey. The only references that cite his tribe say he was Balaw, and that he was related to Garad Abun, the Garad of Hobat. Hobat is the centre and traditional capital of the Karanle Hawiye. Balaw is a clan of Karanle, and is the one that lives around Hobat.
The Futuh states that Ahmed Gurey began as a knight in Garaad Abun's army. Now, this doesn't mean that Ahmed Gurey was Hawiye, because it's also possible that Balaw became Hawiye later on, due to the process of clan assimilation, and may have been a separate and possibly not even Somali clan at the time, and became a Somali Hawiye clan later on. This is similar with the Walashma dynasty, who's Somali name is Wilinwili. The descendants that exist today trace to Ogaden, but this too may be an assimilation or that was always their descent.
This is exacerbated by the fact that in the middle ages there was no concept of a Somali nation, so if Ahmed Gurey traced his ancestry to Hawiye and the Walashma traced their ancestry to Ogaden, that didn't mean they considered themselves to be Somali, a nationalist concept that did not at the time exist. The "identity politics" at the time was very much around religion, with the two sides in the Futuh being clearly the Christians against the Muslims.
I hate uneducated emotional nomads who just talk nonsense.
