Notes:
The arms of Glasbrook as given by Burke's General armory are: Or a lion passant sable on a chief gules three fleurs-de-lys. The crest, however, is: A demi lion gules ducally crowned or. The motto is that of Blayney. The arms of Blayney are Sable three nags heads erased argent, and the crest is A horse's head couped bridled gules on the forehead a piece of armour with a projecting spike proper. These coincidences are surely not accidental.
