Usually when Russians write their name, they write:

Given Name + Patronymic Name + Surname

Given name: Vladimir

Patronymic name: Alexandrovich (son of Alexandr)

Surname: Putin

The patronymic name and surname changes between male and female.

What is not clear is why Igor is not written as Igorevich.

Perhaps a Russian/Ukrainian user can weight in?
