I saw a description of Harar residents and it matched Somalis , idk who posted it. As for Hararis not even they know what is in their bloodWhen and how did Hararis first came to be anyways? I recall somewhere that they are descendant of various Ethio-Semitic and Cushitic groups in Hararghe meaning they might partially be descendant of Harla too. Their language also has a Sidama substratum apparently.
