i asked this question in a thread before, but now i can't recall the answer.
i noticed over the years that many players in the serbian men's and women's NT have the same surname. are any of them brother/sister duos?
i.e. starovic, krsmanovic, rasic, etc.
Sanja Starovic and Sasha Starovic as OPs are sister and brother.
Milena Rasic and Milan Rasic as MBs aren't.
Two Krsmanovics as MBs aren't.
Two Rosics as liberos aren't.
Two Bjelicas (Novica and Ana) aren't.
Add:
Aleksander Brdjovic and Aleksandra Brdjovic as setters are brother and sister. They are both Dejan Brdjovic's children.
I think Bianka Busa has younger brother who plays in junior NT.
Sisters - Tijana Boskovic & Dajana Boskovic
Nikola and Nina Rosic are brother and sister actually.
Ana Bjelica's brother and sister(Milko&Milka Bjelica) are basketball player who play for Montenegro NT. I guess, Ana is form Montenegro as well.
