It's a tiny point and not, I'll be the first to admit, closely related to the article, but how is Ivan Lermolieff an anagram of Giovanni Morelli? Where does the G go, and where do the Fs come from?
I'm quite peeved as well.
I tried alternate, creative, latin-y spellings (josef, ioannes, etc), hit wordsmith.org too for some bruteforce help, no way.
It's an anagram and then he also "Russianized" it apparently, adding the -ff as what we now mostly transliterate as -ov.
