Property of the National Trust, Trerice, Cornwall. Arms: Quarterly of sixteen:

• 1: Quarterly of 4: 1&4: Sable, three crescents argent (Harris of Radford, senior branch of the family); 2 & 3: Sable six martlets Argent (Arundell of Trerice)

Clearly the tinctures are different, but the charges are compatible. This was one of the most important heiresses married by the Harris family, thus the arms should feature in this position, certainly before Daviles, a later Harris heiress.)
