Patronymica Britannica (1860)
MARIOTT. Marletus seems to have been a personal name. In Domesd. one Alricus Marieti sune — Alric, the son of \Iariet — occurs as an undertenant in many counties. See Ellis, Introd. ii. 10. De Gerville thinks it is a derivative of Mary. Eng. Suvn. ii. 83. There is, however, a parish in Somerset called Merriott. See Marriott.
