Marigold Cotton, née Gamgee was born in 2986 of the Third Age.

Marigold was the younger sister of the famed Samwise Gamgee. She wedded Tolman (Tom) Cotton, eldest son of Farmer Cotton and brother of Rosie (to whom Samwise himself was wedded), thus further strengthening the links between the Cottons of Bywater and the Gamgee/Gardners of Hobbiton.
