The "Little Black Book" - in it the names of most of Hajji Ali's ancestors. Upon verification through Hashimite geneaology offices throughout the Middle East, I found that his lineage is missing a few names between "Abdulaziz" and his Idrisi ancestors. Hopefully, with further research the missing names will be discovered.

Silte, Ethiopia - The Tomb of Hajji Aliyye
The Rector of the tomb carries the lineage of Shareef Ali in his chest pocket - at first he denies knowing any knowledge of the noble lineage (fearing I may steal it) but after my uncle clarified that I was in fact a descendent of Hajji Ali - he took out the small notebook and began reading the names of our ancestors.

A copy of the manuscript Futuh al-Habasha by Shahab al-Din Ahmed b. Abdul Qadir "Arab Faqih." I copied it in the Asad Library in Damascus, Syria.
According to the Silti tribe and the Shareef's descendents, the manuscript mentions Hajji Aliyye who is buried in the mountains of Silte, Ethiopia. If there was any basis to this claim, the person would be a man mentioned as "Shareef Ali b. Umar al-Hasani." However, recent investigations has led me to question this Silti claim as well as the historical setting of Hajji Aliyye's migration. He most likely migrated to Silte lands with his own military movement years after the conquest of Ahmed Gran.
