I was asked to provide a new image of the arms for the online Burke's Peerage & Baronetage because the one at present used is that of the late Baroness, mother of the present holder of the title. Lord Dudley has his father's arms and has brought in those of his mother's family in the scheme of quarterings which has been approved by Garter. The image for Burke's will be in grayscale but for the purposes of my weblog I have illustrated the arms in glorious colour.
