Arms of Alan la Zouche (1205-1270) and Ellen de Quincy (?-1296)
From p81 of Lacies Nobilitie by Sir John Ferne (1586)
Blazon: Per pale baron and femme gules thirteen bezants 4, 3, 3, 2, and 1 and a canton ermine and gules seven mascles conjoined or 3, 3, and 1
The la Zouche arms have virtually always involved some number of bezants, but how many depends greatly on the source. The most common is probably ten in pile or 4, 3, 2, and 1, but thirteen or fourteen also occur, and some authorities simply describe them as bezanté, or deliberately unspecified.
