Mà ©mbi is regarded as the mother of the Gékà ©yà © people. The word Mà ©mbi can be translated as the creator, "one who moulds/creates/builds". She and Gékà ©yà © were married, and both are claimed ancestor to all the Agékà ©yà © people. The story of Gékà ©yà © and Mà ©mbi has been recorded by various writers throughout the Gékà ©yà © orator and history; notable among them are Jomo Kenyatta, the first president of independent Kenya, Louis Leakey and the prolific Gékà ©yà © writer Gakaara wa Wanjaà © and another Gékà ©yà © writer known as Mathew Njoroge Kabetà © among many others. The name Mumbi comes from the Bantu root verb KUMBA, "BA", the same root word that gives rise to "UMBA". The prefix "Mu" is the Bantu noun classifier for nouns that have souls, like humans. The verb UMBA indicates the action of moulding, shaping, designing or creating. The suffix "i" replaces the terminal "a" in the Bantu language noun or verb to create the name for the performer of the action. Being derived from a Bantu root, the word Mumbi is also widely used by the Kamba ethnic community. Among the Kamba community, the name carries the same meaning as among the Kikuyus.
The story of the origin of the Agékà ©yà ©:
God (Ngai or Mà ©gai â The Divider/sharer/Giver) created Gékà ©yà © and Mumbi, the founders of the Gikuyu nation. The nation is named after Gékà ©yà © the patriarch [A-Gékà ©yà ©] but by courtesy refers to itself as (Nyumba ya Mumbi). According to one of the myths God took Gikuyu on top of Kéré-Nyaga (Mount Kenya) and showed him all the land that he had given him: West from Mount Kenya to the Aberdares, on to Ngong Hills and Kilimambogo, then north to Garba Tula. He further promised Gikuyu that he would bequeath him all what Gikuyu laid his eyes on. He then pointed to him a spot full of Sycamore trees (Mà ©kà ©yà ©) and he commanded him to descend and establish his homestead on the selected spot known as Mà ©kà ©rwe wa Gathanga (in present-day Muranga County). When Gékà ©yà © descended to the spot he found a beautiful woman Mà ©mbi, the founding Goddess of the nation. Together, Gékà ©yà © and Mà ©mbi had nine beautiful daughters: Wanjirà ©, Wambà ©i, Wanjikà ©, Wangà ©i aka Waithiegeni, Wangeci aka Waithéra, Wanjeeri aka Waceera, Nyambura aka WakÃ©à ©rà ©, Wairimà © aka Gathiigia, and Wangaré. These nine deities/daughters founded the nine Kikuyu tribes. Gikuyu and Mumbi had a tenth daughter named Wamà ©yà © aka Warigia, who as a result of having a child out of wedlock, so the story goes, and went on to found or establish the Akamba nation. Not much is said about her and how she founded the Akamba nation. All the ten daughters' names are very popular names for Gikà ©yà © females to this day, linking them to their original mothers.
When the time came for the 9 eldest daughters to marry, the youngest Wamà ©yà © not yet being of age, Gékà ©yà © prayed to God under a holy fig tree (Mà ©kà ©yà ©, some say Mà ©gumo), as was his tradition, to send him sons-in-law. He offered a lamb as sacrifice and as the fire was consuming the lambâÂÂs body, nine men appeared and walked out of the flames. Gékà ©yà © took them home and each daughter married the man who was the same height as she was, and together they gave rise to the nine of the full-nine clans to which all Gékà ©yà ©s belong. Wamà ©yà © or Warigia got a child out of wedlock. These nine tribes are the Anjirà ©, Agacikà ©, Ambà ©i, Angà ©i aka Aithiegeni, Angechi aka Aithérandà ©, Aacera, Ambura aka AakÃ©à ©rà © aka Eethaga, Airimà © aka Agathiigia, Angaré aka Aithekahuno and Aicakamà ©yà © and all clans and families emanate from them perpetually, through patriarchy.
The Agékà ©yà © refer to each other as Andà © a Nyà ©mba ya Mà ©mbi or people of the house or home of Mà ©mbi. Shortly before a state of emergency was declared by the imperialists in colonial Kenya on the night of 20 October 1952, the name of Mà ©mbi was invoked as a rallying call to unite the Agékà ©yà © in a fight for the independence of Kenya, under the banner of what came to be known as Mau Mau Uprising. Gakaara wa Wanjaà © published the Gékà ©yà © and Mà ©mbi creed, for which the colonial government put him in detention till 1960. Parallel to that several song books would be published under the name of Gékà ©yà © and Mà ©mbi.
Mà ©mbi is used as a female Gékà ©yà © name.
