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.
Blazon: Argent on a cross flory sable between in chief dexter two swords in saltire and sinister two keys in saltire, both azure and gules, five bezants
Crest: On a mural crown or a fountain between a branch of oak leaved and fructed and a branch of beech slipped proper
Supporters: On the dexter a lion sable and on the sinister a horse argent each with a cross formy fitchy pendant from a collar counterchanged
Mantling: Sable lined argent
Motto: Ad summa nitamur (Let us strive for perfection)
The cross flory comes from the arms of John Whitgift, Archbishop of Canterbury, by way of the County Borough of Croyden. The keys and swords refer to the Abbey of St. Peter and St. Paul. The fountain symbolizes the source of the River Wandle, and the white horse is from the arms of the Earls of Surrey.
