Roman's Mother is the unnamed mother of Roman Bellic and the unnamed aunt of Niko Bellic. Despite being frequently mentioned by both Niko and Roman, she makes no appearance or impact in Grand Theft Auto IV.
According to Niko Bellic, he and Romasn were mostly Roman’s mother raised both of them. When the Yugoslavic Wars came, she used all of the money she had saved to send Roman to the United States of America. She also wanted to send Niko to the U.S., but he stayed to fight in the war. In a conversation with Kate McReary, Niko says that he found Roman's mother raped and murdered, although Niko told Roman that she died in a house fire as he thought that telling Roman the truth would be too depressing.
