Grace (style of address)
His/Her Grace is a style of address used for high ranking persons including nobility and royalty. The title was used by some monarchs of the countries of the British Isles before the act of union, such as Kings/Queens of the Scots and English monarchs, prior to the rule of Henry VIII. It is a commonly used title for the nobility of many nations and used for royalty where it is not appropriate to use a style such as His/Her Majesty.
