Those who at the time are entitled to the style His or Her Royal Highness (HRH), and any styled His or Her Majesty (HM), are normally considered members, including those so styled before the beginning of the current monarch's reign. By this criterion, a list of the current royal family will usually include the monarch, the children and male-line grandchildren of the monarch and previous monarchs, the children of the eldest son of the Prince of Wales, and all of their current or widowed spouses.
