One my colleague's name is Valentina Petrovna. That means that her father's name is Peter. I call her just Petrovna. People find it funny when I tell them that Pushkin's line:"Люблю тебя, Петра творенье" (I love thee, Peter's creation) is dedicated to her. Originally it is dedicated to Saint Peterburg in http://en.wikipedia.org/wiki/The_Bronze_Horseman_%28poem%29.
