If the man is called Mr Иванов is his wife to be called Mrs Иванова? i.e. the surname has to reflect gender?
Does this also apply to unmarried women - e.g if the girl's father is Илья Петрович Иванов she should actually be called e.g Эльвира Ильева Иванова? (assuming her first name is Эльвира)
Also - how do female first names decline? e.g Марина - will this be like the feminine noun ending in -а or like an adjective?
