Roger de Mandeville

Roger de Mandeville was a prominent 13th-century noble. He was a son of Agatha, daughter of Robert Wardone and Aufrica de Say.

Upon the death of the Margaret, Maid of Norway in 1290, Roger became one of the competitors for the Crown of Scotland, deriving his claim from his great-grandmother, Aufrica, illegitimate daughter of William the Lion and Isabel d'Avenel, the wife of William de Say.^[1][2]
