Yep. Which is why I think, or believe let's say, that they're Jewish/Christians and seems very likely since Axum conquered SL and Djiobuti. If u read the website it goes into further detail.Some clans in Somaliland such as Yibir are well known to have been Christians/Jews before the expansion of Dir Muslims from the coast. Yibir literally translated to "Jew" in old Aff Sooomali, they are considered to be the original inhabitants of Woqoyi Galbeed. Might I add Yibir and others were their own ethnicities, becoming assimilated into the Somali confederation once the Dir Jihadist conquered them.
If Yibir origins don't come from Axum idk where else they would come other than Yemenite-Jews. Highly doubt they landed on the Somali coast from abroad since Somalia didn't have any trade at the time, but maybe they're ajnabis that landed around the southern coats of Axum and moved down to Somali areas.
