I am currently researching information about my late grandfather, Maksim Culum /  ĆulumoviĆ. I have found that he was Serbian but was born in BRĐANI, Bosnia. The last place he had lived was Jajce prior to WW2. He had fought with the Chetnik units and was displaced following the end of war and had resettled in the UK. I have recently found that he had a wife, Stojanko and daughter Zorka. The last information is the they were living in Bijelo Polje, Montenegro around 1950. Names of  interest are Ostoja, Petra, Zorka, Mira, Borka, Sava and Rosa.
