Huh, that's interesting. "Ivanov" was going to be my guess for Russia, followed by maybe "Kuznetsov" - but the actual result here is "Ivanova", which is the feminine version. (In Russia, your last name changes based on your gender. If Irina marries Ivan Ivanov, her last name will become Ivanova. This is considered to be the same last name. And yes, it can cause annoying issues when traveling abroad, especially with children, when your last names don't seem to match.) I wonder if it has something to do with the slightly higher-than-average male mortality rate?
