Every military barrack in Nigeria has a place called "mammy market" a place close to the barracks, where soldiers’ interact and buy their daily needs.
In 1955 at Enugu, the market was named after Mammy Ochefu, the wife of late military Governor of defunct East-Central state, Col. Anthony Aboki Ochefu, where she sold a local non-alcoholic beverage called enyi to support her family.
After taking a week break at home due to complaints from people that the drink attracted flies, pressure from her clients inspired a Lieutenant Colonel to build her a kiosk to make it more conducive. Her family was later posted out of Enugu to Abeokuta but Mammy continued the business wherever they were posted to while she added snacks that would interest the soldiers.
Mammy registered her business as “Mammy Market” in 1971. By the time her husband retired, the business had grown into a supermarket and a transport business.
When her husband rose to become a military governor, Mammy was still going about her business. She joined him few months later due to pressure from people, leaving the business in the hands of four people.
