Mosi is of African origin, specifically from the Bantu peoples of South-Eastern Africa. It translates to 'like rain' in Shona, a language spoken in countries like Zimbabwe and Zambia. The name Mosi was popularized by the renowned writer Chinua Achebe, who used it as a character's name in his novel 'No Longer at Ease'.
Mosi had 11 children named Ann between 1974 and 1977, with a gap of three years before resuming childbirth.
