Before I met my husband I never knew a Dalibor. It is almost nonexistent in America. However, he informed me it is extremely popular in Serbia - think of it as the Daniel of Serbia. The correct pronunciation is Dal-eee-bor. However, he grew up in America, so he pronounces it Dal-ihh-bor. Two nicknames for Dalibor are Darko - the Serbian nickname, and Dan - the American nickname.
