Are you kidding?
I would never say that Marlen Dovar is Russian name.
If you are serious:
First names:
Alexander (Sasha), Vladimir(Vlad), Ivan (Vanya), Sergey (Serega), Anton, Michail (Misha), Igor, etc...
Family names:
Smirnov, Ivanov, Kuznecov, etc...
Only Hollywood uses "...vich" as the end of Russian second names. It is Polish, sometimes Jewish but never Russians.
In Russia we ususally use 3 names - first, middle and the family name. And most of the middle names have "...vich" ends, but it is nothing more than form of my father's name. It is not our second name. And in the most cases you don't need to use middle name, if you don't speak Russian.
For example. My name is Victor. My family name is Ivanov. My father's first name Sergey. Most of the time they would call me Victor Sergeevich (My first name and my father's name as the middle name). Some times they would call me Victor Sergeevich Ivanov, but it's a little be official. Abroad they would call me Victor Ivanov, it's ok but it looks a little bit disrespectful for native Russians.
