Mariatu was the youngest of three daughters of Chief Yembe of the Royoke village and his youngest wife. She was born in 1938.
In 1954, she met a young officer stationed in Sierra Leone, Lieutenant Alistair Gordon Lethbridge-Stewart, and together they fathered a son, Mariama. Mariama was the father of Kadiatu, who was the namesake for the late 21st century child Kadiatu whom Yembe Lethbridge-Stewart adopted. (PROSE: Transit)
Mariatu went on to marry Kandeh, and together they bore a daughter, Aminuta. Both Mariatu and Kandeh were open about the heritage of Mariama, and in 1963 Mariama and Kandeh finally bonded over a game of football - Mariama was unaware that, in this instance, Kandeh's body was inhabited by his real father, Alistair from 2011.
