Thank you for confirming the house, Alexander.

I’ll make a note of the Vinogradov article you mentioned.
As to the other one, I’ve not yet read anything in English that mentioned Wellington staying in the Winter Palace, though he visited it frequently to have audiences with the Tsar.

Either way if the article is in Cyrillic I must rely on the kindness of others, I’m learning the alphabet and enjoying some success, but haven’t progressed to understanding the language yet.

Josh.
