The British Royal Family is the family group of close relatives of the monarch of the United Kingdom. There is no strict legal or formal definition in the UK of who is or is not a member of the Royal Family, and different lists will include different people. However, those carrying the style Her or His Majesty (HM), or Her or His Royal Highness (HRH) are normally considered members. By this criterion, the Royal Family will usually include the monarch, the consort of the monarch, the widows of previous monarchs, the children and male-line grandchildren of the monarch and previous monarchs, the children of the oldest son of the Prince of Wales, and the wives or widows of the monarch's and previous monarchs' sons and male-line grandsons.
Different terms may be applied to the same or similar group of relatives of the monarch in his or her role as sovereign of any of the other Commonwealth realms. For example, for Canada the family is known as the Canadian Royal Family.
