Superb detective work, barmy, but sadly she died in 1850, not 1849 ...
This has been a fiendishly fabulous quiz - 105 questions, including anagrams, dingbats, heterographs, odd one out, connections and mathematical problems - and 25 pictures - great fun, but I'll be glad to get my life back!
This is the only question I haven't been able to answer, so obviously I'm disappointed not to get a full house, but thank you everybody for trying to help me - it really is very much appreciated
ps I'll post the answer once the quizmaster releases the results sometime in September
