Btw , I made an error : the cairns and the archeological sites discovered around the Wajir area most likely belong to a Proto Sam or Somaliod Eastern Cushitic group . Some of the cairns and burial sites discovered in Northern Tanzania by the ancestors of the Iraqw are different to the burial sites found in South Somalia ( now referred to as Northern Kenya ). I will touch on the Madanle people of Southern Somalia and the decline of the Cushitic reign in Kenya /Tanzania at another point .http://danstiles.org/publications/archaeology/3.Azanian (MSAFIRI 46).pdf

Seems like the Azanians were a South Cushitic group.
