Wanjiku should not be confused with Wanjiru.
Wanjikũ is a feminine Kikuyu name. Historically, Wanjikũ was one of the nine daughters of the man and wife who founded the Agĩkũyũ people, Gĩkũyũ and Mũmbi. Consequently, the descendants of her lineage form the Agacikũ Clan of the Agĩkũyũ tribe in Kenya.
