Alexander of Russia, the patron saint of the Cobourgs, was dead, so Alexandrina of England, named in honour of him, gave way to Victoria the tutelary deity of his (when living) subservient Cobourgs. Both names are alike foreign and unharmonious to British ears,* although of the two, Alexandrina perhaps the most euphonious. *George IV., who, whatever his faults, had a true British spirit and sentiments, declared both to be anti-British, and expressed himself in no measured terms at the time about giving the royal infant such unEnglish names.
