I am glad that the Croats also consider me their own because my ancestors are Croatian Draganović family from Zadar. As Croatian nobles in the 16th century, they came to Lika and stayed there. In Lika, my obstacles came through Novi Vinodol.
My mother's ancestors, the Kalinics, are also Croatian nobles from Novi Vinodol. Due to circumstances, my great-grandfather had to go to the Bosnian Krajina (Turkish Croatia) and there he married an Orthodox girl and converted to Orthodoxy.
