The name SEDGWICK was probably a correction given, like many others, through a wish to explain the meaning of a name (Siggeswick), the real import of which was quite forgotten.  The word Sedge is not known in the northern dialects of England, and the plant itself does not exist among the Yorkshire valleys.  But a branch of the clan settled in the low regions of Lincolnshire, and seem to have first adopted the more modern spelling, and at the same time began to use a bundle of sedge as the family crest.  This branch was never numerous, and is now believed to be entirely extinct.  Indeed, the Sedgwicks never seem, at least in England, to flourish away from their native mountains.   If removed to the low country, they droop and die away in a few generations.  A still older crest, and one suited to the history of the race, is an eagle with out-spread wings.  Within a comparatively few years, eagles existed among the higher mountains on the border.   The armes most commonly borne by the Sedgwicks, and accorded to them by Burke in his Encyclopaedia of Armorial Bearings, are composed of a field or, a cross gules, with five bells of the field, and a lion passant through sedge on a cap of maintenance.  ~ ROBERT SEDGWICK, of New York City.
