Matthew Paris
These arms were attributed to William III de Braose (d.1211) by Matthew Paris in "Historia Anglorum, Chronica Majora", Part III (1250–59) British Library MS Royal 14 C VII f. 29v (shown there inverted to denote his death): "Party per fesse gules and azure, three garbs or". Matthew Paris is not generally regarded as a reliable source for heraldry and these arms must be considered doubtful.
