Two of our friends recently got married. The husband is Russian and his wife took his last name. In the Russian culture, the wife feminizes (???) her laat name. So for example his name is Alex Petrov, so she marries him and becomes Jane Petrova. How do I address mail to them? I think the obvious answer would be to write out both names in full right? But what if I wanted to write out Mr. and Mrs. P? Would it be incorrect to write it out as Mr. and Mrs. Alex Petrov?
