Really?
Here’s summary of how far back you have to go to get to a direct ancestor in the royal line who was born in Hanover:
Charles III: born Buckingham Palace, London, England
Mother: Elizabeth II, born Mayfair, London, England (1926)
Grandfather: George VI, born York Cottage, Norfolk, England (1895)
Great-Grandfather: George V, born Marlborough House, Westminster, England (1865)
Great-Great-Grandfather: Edward VII, born Buckingham Palace, London, England (1841)
Great-Great-Great Grandmother: Victoria, born Kensington Palace, London, England (1819)
Great-Great-Great-Great Grandfather: Edward, Duke of Kent and Strathearn, born Buckingham House, London, England (1767)
Great-Great-Great-Great-Great Grandfather: George III, born Norfolk House, London, England (1738)
Great-Great-Great-Great-Great-Great Grandfather: Frederick, Prince of Wales, born Hanover, Holy Roman Empire (1707)
Great-Great-Great-Great-Great-Great-Great Grandfather: George II, born Herrenhausen Palace, Hanover (1683)
So the most recent ancestor in the direct royal line born in Hanover was Frederick, Prince of Wales, born in 1707. That’s 317 years ago.
Every direct ancestor in the royal line since then has been born in England, starting with George III (1738), 287 years ago, who “gloried in the name of Briton”.
The last direct ancestor of Charles who was King of Hanover (but never visited) was George III, who died in 1820, 204 years ago.
The last time someone in the direct line married someone from Germany was Victoria, who married Albert of Saxe-Coburg and Gotha (not Hanover) in 1840, 186 years ago. Every spouse since then has been born in England, except for Alexandra of Denmark (spouse of Edward VII)
Yup, they’re basically Hanoverians, no disguising it.
Tell me, if you met someone in England, the US or Canada today whose last ancestor born in Hanover was in 1707, whose direct line has been born in England, the US or Canada ever since, and whose last German ancestor was from 1840, would you say that they’re basically Hanoverians, not English, Americans or Canadians?
