@Ivan we have unique surname and it is really easy to track our relatives.
@Xilaw yeah well, we are largest clan so it is logical that our people are scattered all over the region, especially in Serbia.
btw, I remember once watching the talk show on some Serbian tv, the guests were politicians mostly. at one moment in the middle of the show  they started arguing who of them has ancestry from this or that Montenegrin clan. it was hilarious. But it shows how connected our people are.
