'Shanshiyo (Somali: Shanshiyo Arabic: الشاشي) or Shaanshi is a Banaadiri clan, mainly from the southern coastal cities of Mogadishu, Marka, Baraawe and Kismayo[1] which established communities in the hinterlands in towns such as Baidoa and Diinsoor due to trading.
The clan traces its ancestry to Abd al-Rahman ibn Awf,[2][3] a close companion of Muhammad.
This group along the Benaadir coast first settled in the old quarter HamarWeyne and can still be found predominantly living in the houses around the masjid Awooto Eeday.
[4] All Shaanshiyos in Banaadir ancestry trace back to the common ancestor Abubakar Qaffal al-Shashi (from Shaash, which refers to what is now Tashkent)[5]).
In Marka, they are part of the local confederacies called the 12 Koofi (Somali: 12 hats) along with clans such as Duruqbo, Asharaf (Ba 'Alawi, Bin Hassan and Mahdali), Gameedle, Haatim, Reer Khaadib, Shukureere, Juunji, Reer Manyo and Shiikhaal (Gendershe and Jaziira).
