Abusua: how matrilineal descent shapes an Akan family tree
· 6 min read
Most genealogy software was built around a European assumption: that a family line runs through fathers, and that a surname marks the line. Among the Akan peoples of Ghana and Côte d'Ivoire, it does not. Descent runs through the mother, and the group you belong to for life is your mother's abusua.
If you are recording an Akan family and you only capture parents, children and surnames, you will produce a chart that is technically correct and genealogically hollow. The relationships that mattered to the people in it will be missing.
What the abusua is
The abusua is a matriclan. You inherit it from your mother, she inherited it from hers, and it continues unbroken along that line. Your father's abusua is not yours, and his relatives, though close to you socially, sit outside your lineage in the traditional reckoning.
Akan tradition recognises eight of these clans, though names and spellings vary between Asante, Fante, Akuapem and other Akan groups, and some are known by more than one name:
- Oyoko
- Bretuo
- Agona
- Asona
- Aduana
- Asenie
- Asakyiri
- Ekuona
Because every member of an abusua is understood to descend from a common ancestress, two strangers who share a clan will often describe each other as family, even with no traceable link. That is not loose speech. It is the descent system working as intended.
The father's line still matters
Matrilineal does not mean fathers are irrelevant. In Akan thought a child receives ntoro, a spiritual inheritance, from the father, alongside the mogya, or blood, received from the mother. A complete record of an Akan person therefore carries two distinct inheritances, only one of which determines clan membership.
Inheritance, and what changed in 1985
Historically, property and office passed within the abusua rather than from father to son. A man's successor was typically his sister's son, since that nephew shared his clan while his own children did not. Understanding this explains a great deal of what otherwise looks strange in older family records and land documents.
Ghana's Intestate Succession Law of 1985 changed the legal default, directing a larger share to the surviving spouse and children. The statute changed the law; it did not erase the clan. For anyone tracing a family across the twentieth century, both systems are present in the record, and which one applied depends on when and where.
How to record it
- Record the mother's abusua for every person, not only for women. It is the field that makes the lineage reconstructable.
- Record the father separately and fully, including his abusua, but do not treat it as the child's.
- Do not infer lineage from surnames. Modern Ghanaian surnames commonly follow the father and will point you away from the matriclan.
- Where a relationship is described as brother, sister, aunt or uncle, note whether it is a clan relationship or a direct one. Both are real, and conflating them corrupts the tree.
- Note your source and the person who told you. Clan membership is usually transmitted orally, and a claim is only as good as its informant.
A family tree is a model of how a family understands itself. For an Akan family, a model without the abusua in it is a model of somebody else's family.
