7. Walter de Cornwall, knight of the shire in 1311, an illegitimate descendant of one of the earls of Cornwall, bore the same arms.[334]
8. Sir Geoffrey Cornwall having taken prisoner the duke of Brittany, received in reward that nobleman’s arms, viz. Ermine, which he made the field of his own, retaining the lion gules, &c.[335]
The descendants of the bastard offshoot of the earls of Cornwall became widely scattered, and, according to the practice of antient times, varied their arms in every house. For example:
9. De Cornewall, and Cornwall of Oxfordshire, bore the red lion of Poictou, debruised by a bend sable, charged with three bezants.
10. Cornwall of Devon omitted all traces of Poictou, but retained the characteristics of Cornwall, viz., On a cross patée sable five bezants.
11. Cornwall of Essex bore the red lion of Poictou, the ermine of Burgundy, and the sable bordure bezantee of Cornwall.
12. Cornwall of Salop bore the same, except that he made his lion reguardant. His descent from the princely stock of Cornwall is hinted at in his crest, which is a Cornish Chough.
In Glover’s ‘Ordinary’ are these two:
13. Cornwayle, Argent, on a fesse sable, three bezants.
14. Cornwall, Argent, on a cross-patonce sable, five bezants.
