In the Isaaq clan-family, component clans are divided into two uterine divisions, as shown in the genealogy. The first division is between those lineages descended from sons of Sheikh Ishaaq by a Harari woman – the Habr Habusheed – and those descended from sons of Sheikh Ishaaq by a Somali woman of the Magaadle sub-clan of the Dir – the Habr Magaadle. Indeed, most of the largest clans of the clan-family are in fact uterine alliances hence the matronymic "Habr" which in archaic Somali means "mother".[26] This is illustrated in the following clan structure.[27]
