Regarding T. georginae & T. caroli I am not sure what the evidence that caroli was named after Charles Lucien Bonaparte is but there is a famous Georgina associated with Napolean Bonaparte that it may have amused Bourcier to named one of this pair of species after:
Marguerite-Josephine Weimer who was a famous lover of Napolean (who nicknamed her Georgina after her onstage character Mademosiele Georges).
Whilst it is clear Claude Marie Jules Bourcier was a Napoleanist, one must remember that in 1847 France was still ruled by the July Monarchy and to blatantly honour any Bonaparte may not have been the best political move.
Just a thought.
Typo/s, or my misinterpretation?
Either way, I have no idea/suggestion on the dedicatee behind georginae. From what I can tell (not much) it could be her, or not.
Maybe Martin has a better candidate, he's been dealing with Hummingbirds (and their Eponyms) for years and years.
