The political units above are likewise grouped into eight larger groups called "abusua" (similar to clans), named Aduana, Agona, Asakyiri, Asenie, Asona, Bretuo, Ekuona and Oyoko. The members of each "abusua" are united by their belief that they are all descended from the same ancient ancestress. Marriage between members of the same "abusua" is forbidden. One inherits or is a lifelong member of the lineage, the political unit, and the "abusua" of one's mother, regardless of one's gender and/or marriage. Note that members and their spouses thus belong to different "abusuas", mother and children living and working in one household and their husband/father living and working in a different household.
