Everyone can claim it. They are copy-cats. Its like how when the prophet came from one tribe, other tribes couldn't handle the fact that another tribe was chosen over them. That's why when the prophet died, they claimed a prophet came from their tribe. Someone has to be telling the truth. All the others have no evidence. Except isaaq and darood. Idk about isaaq but darood has many arabic books written about his lineage and where he was born, what he did before he came to somalia and why he went to somalia. Its the arabs who claim us, it isn't a somali "myth" we made. Its a well-documented thing.
