The Lyme Regis branch of the Burridges was in shipping (including slaving) from various West Country ports and it was to this branch that arms were granted early in 1700. The full achievement of arms reflects the Burridge seafaring: "Azure three dolphins naiant embowed argent, on a chief or three rudders sable. Crest a demi-mariner proper his waistcoat gules cap azure neckcloth argent supporting a rudder sable". These arms are also credited to Burridge of Hawksworth, Kent. A further grant is recorded to William, son of William, of Portsmouth and Chard, later in the eighteenth century.
A family legend about origins in three Danish brothers coming over for the Conquest and being "the bowmen of the ridge", and attributions to nearby Bowditch, I believe the surname derives from the place-name Burridge, of which there are four in Devon (and one in Hampshire). The family story seems to have withstood the uncomfortable but incontrovertible fact that it was the Saxons who held the ridge, in order to force the Normans to charge uphill. The legend has even produced an alternative set of arms, depicting arrows, which at one time was visible in the church at Lyme Regis.
