Inspired by this post, a question popped into my head.Got bored - this happened ...
George II of Great Britain, b. 1683, r. 1727 to 1760, m. Caroline of Ahnsbach
1) Frederick, Prince of Wales, b. 1707, d. 1751, m. Lady Diana Spencer (i)3) William IV of Great Britain, b. 1721, r. 1760 to 1765, m. Maria Amalia of Hesse Kassell (ii)a) Prince William of Wales, b. 1744, d. 1750(i) IOTL, the match was vetoed by Robert Walpole and George II, but here it goes ahead. In turn, in May 1736, the King wishes to visit Hanover but ends up sending Frederick and Diana. On the return, Frederick falls ill with a fever and piles and dies before producing an heir.
(ii) Maria Amalia dies in childbirth with her first child, William, but the child subs
Say, Poor Fred had married Diana, the marriage would've been "morganatic" under terms of the Holy Roman Empire. England wouldn't have ponied up the funding for the hochadel tax to equalize the marriage to keep what was essentially an albatross (and I doubt Fred would have been overly interested in such a scheme either). Butcher Cumberland, marries equally, inherits Hannover and things plod along for a decade or two.
Then William's line goes extinct in the male-line (say, around the 1780s/1790s Cumberland's legitimate son dies and he had only daughters). Frederick is dead, Diana is probably dead, but they have surviving issue (unlike her Bedford marriage of OTL).
Is the "electorate of Hannover" allowed to go extinct in Germany? Or does the king of England get the title? I could understand that it might be dependent on whether or not the Empire needs an alliance with England at the time, but "legally speaking", what would happen to the title?
