Cousin Pearl in the Bryson Bunch supplied the following:
About 350 B.C., there lived a Greek philosopher, Bryson (sometimes Bryson but always with the characteristic Bry), who taught mathematics to Plato.
Bryson Coat Of Arms: "Creighton hue, a salfire between two spars, rowels in Fess, a spearhead in chief or a crescent in base on crest; a hand holding a cowhorn motto 'Ever Ready'." The same crest, ship under full sail "God with my right". Gurl, red. The background of salfire, argent presents the cross of St. Andrew in silver fess. In the center point of the shield a spearhead in chief, clef in upper part of shield, crescent halfmoon in gold in crown of shield.
