That reply is correct, Queen Victoria's second daughter Alice married Louis IV, Grand Duke of Hesse & by Rhine (it was a Grand Duchy that ceased to exist after World War I). The oldest daughter, Victoria, Princess Royal, was the one who married a German prince. She married Frederick III of Prussia while he was still Crown Prince of Germany, so she was Crown Princess of Germany after marrying. She was also Empress for only 99 days, though, because Frederick died after 99 days of being head of the German Empire, so their son Wilhelm II became Kaiser. George V, Queen Victoria's grandson through her eldest son Albert Edward (Edward VII) and his wife Alexandra of Denmark, was the one who changed the house's name to Windsor because Saxe-Coburg and Gotha was a German name and Germany and the UK were enemies back then. Today's British royals would probably be from the House of Saxe-Coburg and Gotha had George V not changed the name (sorry if this reply was so wordy, I really like studying Queen Victoria and her descendants).
