No Digil And Mirifle migrated via shabelle and jubba river to where they currently live, groups that were in south before them are like Eyle, Gawaawiin, Shiidle , Makanne , Kaboole etc and Maadanle, Maatire and their likesLamagoodles originated in the north, while D&M originated in the south. I read this theory that both of them are descended from a proto-Somali population that lived in southern Ethiopia.
