Yes, a lot of archaic names which are very rare. Also, Russia is multinational country, so Russian (as in ethnicity) and Russian (as in nationality/citizenship) names are different things. A lot of names (but not family names) are actually Tatar, Armenian etc. A combination of that name with typical Russian family name is not unheard of, but pretty rare to attract the attention which is the last thing you want if you use fake name for any serious purpose.
