You also need to type your current surname and your father’s name together with your first name and surname.
Standard Russian names: first name, patronymic, last name
First name: You can choose any one. It all comes down to personal preference. I really can’t choose one. There are traditional names in the Russian dictionary, so I can call them whatever I like.
Patronym: It is the pronunciation of your father's name with a slight change. There are fixed changes, maybe it really can only be a certain baby.

Last name: This goes The pronunciation of each one remains the same. If it changes, I feel sorry for my ancestors!
