I had a case at work. One day I spoke with a man named Petrovich and the next day I spoke with a man named Mikhail. Here we in the office dreamed that the daughter of one should marry the son of the second, and give the children a double surname. Maria Ivanovna Mikhail Petrovich, in my opinion, great.
Mikhail Petrovich Mikhail Petrovich - this is the perfect result.
