Zybin

Just a quick sidestep since we mentioned the Russian aristocratic family Zybin, a Russian noble family, which, according to the legends of ancient genealogies, descended from the Prussian-born Andrei Zyba, who moved to Veliky Novgorod in the second half of the 14th century.

Notably that the Zybins are mentioned by famous writer Pushkin in one of his essays to be close to tsar Ekaterina the Great and by L. Tolstoi.
