He has 20% Somali in him according to 23andMe and he doesn't believe that he has 20% Somali? lol that is funny. Tell him bro the DNA doesn't lie, you got 20% Somali in you. Some Somali's got Ethiopian in them too. I've seen Somali's with up to 20% Ethiopian in them.
He said, where he came from there are no somalis living there, he lives now in USA but he and his family are from two cities Wollo and Shewa. According to him, he is amahara and he does not know of any somali lineage in his family so he does not believe it.
