`  Laveol: Even last name Kolisev is a Macedonian one. Last names ending with ``ev``, ``ov`` are not Bulgarian. It happens that you have those in Bulgaria. But you have those last names in Macedonia, Russia, Check Republic, and so on.  Kolisev is a Macedonian last name. Same is Kolisevski. You can find both kinds with ``ov|ova``, ``ev|eva``, ``vski/vska``, ``ski/ska`` and others in Republic of Macedonia. So changing a last name from Kolisev to Kolisevski does not have any Bulgarian/AntiBulgarian implications. My last name is ``Janev``. You can find in Macedonia also ``Janevski``, ``Janeski``. All of those are Macedonian last names. The fact that you can have ``Janev`` in Bulgaria does not translate to ethnicity/origin claims in Macedonia.  Here are some last names that finish on ``ov``, ``ev`` and are not Bulgarian neither Macedonian:  [Sergei Lavrov] [Anton Chekhov] [Martina Navratilova]  So these last name endings are typical but not exclusive for some of the Slavic languages. Same is with ``vski/vska``, ``ski/ska``, ``ich`` which are shared between a number of Slavic languages.  To come back to Kolisevski: Kolisevski is a Macedonian last name, as well is Kolisev. If you can find a person living in Bulgaria with one of those last names, and probably you could not, does not gives any conclusion about ethnicity or being a Pro-Bulgarian.   `
