now you may or may not know that Queen Victoria's husband Albert the Prince Consort was younger brother to a Reigning Duke (Ernst II) who died childless in 1893, now under normal circumstances the oldest male in the male line would become the Duke of Saxe-Coburg and Gotha, in this case that would be Albert Edward, Prince of Wales (Edward VII), however the constitutions of two the duchies excluded the king and heir apparent of Great Britain from the ducal throne if other eligible male heirs existed and Albert Edward had renounced his claim to the throne in favour of his next brother, Prince Alfred, Duke of Edinburgh. so Alfred became Duke in 1893. is there a way that Albert Edward could of became Duke as well as King? and what does that do to the UK to have a new Crown Union?
