Genealogy of the British Royal Family

The recorded genealogy of the British royal family traces back to the early Middle Ages. Although there is no strict legal or formal definition of who is or is not a member of the royal family, and different lists will include different people, those carrying the style His or Her Majesty (HM) or His or Her Royal Highness (HRH) are generally considered members. The current British royal family are members of the House of Windsor.

Ancestors of Edward VIII and George VI.

The family and ancestors of Queen Elizabeth II.

The name "Mountbatten-Windsor" legally applies only to the descendants of Queen Elizabeth II and Prince Philip, Duke of Edinburgh, who do not carry the "HRH" title. Therefore, the only technical holders of the name to date are the children of Prince Edward and his wife the Countess of Wessex- even though they are entitled to the HRH status they do not use it, making them the only 2 current people to be able to use the Mountbatten-Windsor surname, as everyone else by Letters Patent are actually Windsors.

Ancestors of The Duke of Edinburgh.

Ancestors of Sophia of Hanover.
