Since the memory of men slips away swiftly, lest any difficulty of controversy should arise over this among those to come, we, Edward, by the right of arms King of the East, and Thyra, by agency of the same right our Queen, do by these present letters signify to the future as well as the present, that, by the counsel of illustrious persons concerning the good works of Matilda Wynter, we find the said Matilda to be noble, faithful and deserving of such rewards as are within our sole and lawful authority to bestow.  We do therefore give, endow and award the said Matilda with arms in the form and matter set forth herein: Ermine, a chevron cotised gules.  And we do further decree, instruct and ordain that the said Matilda shall bear these arms singularly and in perpetuity, free from every disturbance of whatever power.  That this our charter shall remain hereafter firm and unimpaired, we have ordered it to be marked with our signs manual upon 1 November at Stonemarche in the forty-ninth year of the Society.
