groups: on the lower reaches of the Shebelle in Audegle District around Dolo on the upper jubba, between the Webi Gestro and the Webi Mana in contact and to some extent intermixed with the Arsi Oromo, and to the south-west between the Ajuran and Degodia Somali and the Boran Galla of the Northern Frontier Province of Kenya. The northernmost group adjacent to the Arsi Oromo have acquired some features of Borana Oromo culture; Galla and Somali are both spoken. Arsi Oromo villages are intermixed with those of the Garre (Gurra) but are kept separate from those of the Somali. The Garre (Gurra) of this region have traditions similar to those of the other Garre groups and consider themselves Somali rather than Galla. Garre traditions generally recount movement southwards from the North-west corner of British Somaliland. As a whole, the Garre are nomadic pastoralists with large numbers of camels, sheep, goats and where the habitat is suitable, they settle and domesticate their cattle. Proto-Reewin The Proto-Reewin group were probably the first Cushitic group to enter what is the southern part of modern day Somalia, around the end of the second century B.C.. The Proto-Reewin, the ancestors of the modern Reewin families (Digil and Mirifle), occupy a unique position both linguistically and culturally in the historical development, migration and settlement in the area south of the Shabelle River. The name is not pronounced "Rahanweyn" as traditionally suggested, but "Reewin". It is a compound name which can be divided into ree=reer=Family; "win=weyn=old" "the old family". This definition of the name Reewin might indicate that Reewin (Digil and Mirifle) might have once been the first Somali speaking group that established itself in what is today modern Somalia, whence the rest of the Somali clans diverged slowly and through time developed their distinct northern dialect. But since the northern Somalis were separated from the Reewin-speaking people for at least 1500 years, their language might have undergone a mutation process Rahanweyn tribes are aggregates of many diverse clan attached to a small original nucleus of Rahanwein, who form the dominant eponymous clan and provide the skeletal framework in each tribe. In many cases, however, this type of organization, dependent for its structure on a dominant clan, is superseded by a system of territorial groups whose political relations are not expressed genealogically. In the Rahawein family itself there are only three orders of segmentations between the group-name
