It might be just that the clerks decided not to put in a patronymic for you when they examined your father's documents. It might also be that your parents did ask for no patronymic and the fact that you don't know about how it went is pretty understandable, because why would a parent just started talking about a patronymic or in your case its abscense out of the blue, especially to law-related details? And it looks like you didn't care enough about it to ask yourself![]()
