I'm puzzled by Feodora's claim that the king was going to ask for her hand (in marriage), because Queen Victoria's predecessor was William IV (r. 1830-1837) and he was married -- happily and faithfully, by all accounts. He and his wife, Queen Adelaide, never produced an heir. His predecessor, King George IV, had a wife but they couldn't stand each other, had been living separately for years, and she died shortly after he acceded to the throne (1820). So apparently it is King George IV that Feodora is referring to. However, when he became king she would have been 13 years old. I suppose the idea that the 50+ king could marry a teenager was not too far fetched. OK, I guess I have answered my own question.
