Mary Mitchell Slessor

"Mma" — Scottish Missionary Who Helped End the Killing of Twins in Okoyong (Cross River)

Summary

Scottish Presbyterian missionary who arrived Calabar in 1876 and spent 39 years among the Efik, Okoyong and Ibibio peoples until her death in 1915. A former Dundee mill girl with no formal theological training, she learned Efik, lived in mud huts on the same diet as her hosts, and travelled alone deep into territory closed to European men. She is most widely credited with helping to end the customary killing of twins in Okoyong and parts of Cross River — personally rescuing and adopting many of the rescued children. Historians today emphasise that the practice was already declining under combined pressure from earlier missionaries (notably Hope Waddell of the United Presbyterian Mission, present in Calabar from 1846), Efik converts, and Royal Niger Company / Protectorate authority; Slessor's singular contribution was the depth of her witness in Okoyong, where she settled in 1888 and where the practice was most entrenched. She was the first woman ever appointed a Vice-Consul in the British Empire (1892), exercising judicial authority over the Okoyong region, and her work directly inspired the next generation of Britons to come to Nigeria — including [Pa Sydney Elton](/heroes/sg-elton), whose call to mission began after reading a book about her.
