Iam Montenegrin but I do like all the history on the former Yugoslavia in particular that of Serbia, Croatia and Bosnia. Its funny to read the debates over origin etc... What I will say is this we're all from Africa or Adam and Eve so I guess the debate is pointless. 
 Most of the former Yugoslavia is like a Pizza...you will never be able to get all the slices. 
 We're all too mixed. 
 Eg Petkovic, Petkovich, Petkowski, Petkovski, Pekov, Petkova..same name and found in all Slav lands so no point pointing out were different.
