I am researching the Knjeginjic family from Prijedor,Bosnia&Herzegovina. Nikola Knjeginjic first appears in the 1850 census(at that time he had a last name Kovacevic), but I don't know where he was before that. He married Stana Kolar from Crna Dolina, and they had sons Mile,Lako and Pero.
Any information would be appreciated. I am also willing to share the information that I have.
