When the SFG gets stronger and in a more secure position. We should invest $$$ to find the uncorrupted manscript of Futuh Al Habash. The Ethiopians are sitting on historical records concerning Somalis. Alot of things will be discovered. Sade lost majority of their ppl along with Jidwaaq and Geri Koombe. While Harti and Ogadens grow exponentially in the centuries after.Voltage to play the devils advocate since you chased away Benny from you threads, all the supposed evidence you brought was a couple of anecdotal examples as evidence that Silte is related to us, and then you have brought up their claim to the names Abadir and Sade, well that is not exclusively claimed by Marehan anyway, even our own Shieekhal and Murursade have these names in their lineages.
I think as ancestral dna test become more sophisticated we can find out our lost kinfolk in Ethiopia, but as it stands now its too much of a mystery.
I have a theory about this. I assume Sheikh Abadir was a prominent Islamic scholar who was Marehan in the 13th century in Harar. He's real name is Umar as Abadir is a naynees. When the Futuh Al Habasha & Oromo invasions happend. His descendants as religious ulema became confederation for protection as Harar gotten weaker after Emir Nur. He [Abadir] became a famous patron saint of Harar several hundreds before Emir Nur ibn Mujahid came to power. I also assume that due to Sheikh Abadir as the patron saint of Harar which was the preminent Islamic centre in the Horn of Africa. He's descendants such as Daud and Maxamed Daud became the primary chiefs of Marehan and heads of Darood due to their familal connection to the main metropolis of the land. Mind you this round as the same time that Warsangeli Sultanate is in their infancy. As the city fell and Emir Nur ibn Mujahid forced the inhabitants of the city to forget clans and became one people, Adaris. Alot of his descendants became Hararis, Oromos, and Silites due to the forced integration and assimilation of the period. But all records/historical sources indicate that Marehan( Futuh, Ethiopian and European) were a primary military force in Harar and such used that connection to increase their prestige amongst Daroods who they became the Boqor for. Now to the Sheekaals. I think they are the descendants of these lost Sheikhs who some are sheegads and some are lost Marehan. As Sheekaal they are a religious order who became adopted to the Somali clan system. The other ethnic groups they shifted over through the years and others are sheegads due to the famous patron saint of Harar. We [ Emir Nur ibn Mujahid] built the famous Harar gates that are UNESCO world heritage site. Harar is what Lalibela is to the Amhara. Our forebears fought for Islam and the promotion of Islam in Ethiopia. We conquered them.
It's really fascinating when you think about it Saddam. I also think this is possibly what may have happened. When you look at what Abadir is to Islamic history in the area, then look at Marehan geneology where he is in, and then see that ONLY Marehan is observed to have been in Harar/Adal 500 years ago out of all the people who claim him, then see the religious cannotation for the later claims, or that Abadir's descendents also became the chiefs of the MX clan etc etc etc you can't help but come to your theory.
Obviously a lot more research and historical record gathering is needed
It's ok. Once we get into the 1800's you will show up in history. 
. We need to go deep into cisse and ask about their oral history.
