Mamusu "Rose"[1] Grant is the mother of Peter Grant. She is a light skinned Fula from Sierra Leone, who speaks Krio.[2] Her father had several wives; Alfred Kamara is one of her half-brothers.[3] She has a lot of Temne and Susu relatives.[4] Mamusu went to school in Kambia with a girl named Jo who also lives in London now.[5] Before arriving in England she worked at the library in Freetown[6] with Elsie Winstanley.[7]

When Peter introduced Simone Fitzwilliam to his mother, Rose became furious. She recogniced Simone as a woman who tried to seduce her husband Richard years ago. Since Simone still was young, Rose deduced that Simone was an evil witch.[8]
