1 The Lordship of Ireland did not have an official flag. A commission of Edward IV into the arms of Ireland found these to be the arms of the Lordship. The heraldic description is Azure, three crowns Or, bordure Argent. Typically bordered arms represent the younger branch of a family or maternal descent.
