Momoh’s first wife was Ovbianogbo from South Ibie, east of Auchi. She bore a total of 8 children for Momoh the First, including Gimah, who succeeded Momoh the First on the Throne, and Meremu, who was the third Ogbaichi (leader of the women in Auchi including those born in Auchi and those married into Auchi). However, the wife who bore the most children for Momoh the First was the seventh wife, Fati Hassan, from Zamfara State, who had 11 children.

As the family was increasing in size, there had to be an arrangement to allocate food, clothing, supplies and resources for all the wives and their children adequately, Momoh the First instituted an arrangement where the house was divided into three groups for resource allocation: the first group comprised the senior wives, the second group comprised the middle wives and the last group comprised the youngest wives. The eldest wives in the first group were headed by the most senior wife (Ovbianogbo). The wives in the second group were headed by the 11^th wife, Adishetu from Fugar, and the third group was headed by the 21^st wife, Tsefia Omogbai from Jattu-Uzairue Royal Family. The leader of each group was tasked with taking what was meant for each group and managing equitable sharing among the wives they headed. The wives were headed by Momoh’s mother, Iyami, who passed on in 1933.

The second layer of organization was on living quarters. The younger wives lived with the eldest wives, while the middle wives lived alone. The oldest wives supervised and mentored the younger wives and oversaw the raising of their children. This organization was to have profound implications on how the Momoh children related later in life. For example, one of the eldest wives was Osikhomo, the 6th wife from South Ibie, who was the mother of Salmanu, more popularly known as Kessington Momoh. Kessington Momoh was a parliamentary secretary to Chief Obafemi Awolowo and later served as minister in the Western Region; he was indeed a prolific figure in pre-independence Nigerian politics in the 1950s. One of the youngest wives, Anima from Iyekhei, the 34^th wife, lived under the tutelage of Osikhomo. When Momoh the First passed on in December 1944, Prince Kessington Momoh became the “father” of the children of the younger wives who stayed with his mother. Thus, it was Prince Kessington Momoh who served as the grandfather of the children of his own brothers, and these bonds instituted by Momoh the First have endured within the Momoh Family till this day. Such arrangements also led to siblings of different mothers developing strong bonds.
