12. These early charges were commonly animals and included trees, plants and man- made objects such as swords, axes, castles, even articles of clothing. Many of the early armorial bearings were canting arms, that is the charges used were allusive to the name of the family involved. Thus we find De Hertley with a hart on the shield of arms (coat of arms) or roach (the fish) on the arms of the Roche family. Some of the allusions seem difficult to understand. For instance the Raven on the arms of the Corbett family, but this is because the old name of this bird is corbie, probably taken from the French "le corbeau". Likewise lucy, the old name for the Pike, was the charge on the arms granted to the De Lucy family in the reign of Henry III and though the name of Lucy is no longer used we still find it in the scientific name of the Pike, Esox lucius. The Otter, in French "la loutre" was used allusively in the arms of the Lutterel family, though this was superceded by a shield of arms with martlets (Swallows) as charges. The martlet was also used as a mark of cadency denoting a fourth son. There are many other instances of this, the Hedgehog (in French "l'herisson") was used on the arms of the Harris and Harrison family, a Stag Beetle on the arms of the FitzUrse family are just a few of the others.
