Anglo-Norman language
Roger Corbet was the younger brother of Robert Corbet (1383–1420) and was frequently associated with him. However, Roger's very existence is omitted by several sources. He does not figure in the Corbet family pedigrees in the heraldic visitations of Shropshire Augusta Corbet, the family historian, also gives a pedigree of the Corbets of Moreton Corbet which omits him. She quotes extensive complaints to the 1415 parliament, in the original Anglo-Norman language, in which numerous misdeeds are listed, but insists that they refer to Robert's younger son of the same name, who was probably unborn, at most an infant, at that time. It is with his this nephew that he is generally confused.
