Zhutane Roma
A small group of people referred to as the Zhutane Roma emerged in Sofia, Bulgaria, during World War II. They were the mixed descendants of poor Jewish women who married Romani men. This group of Bulgarian Romani Jews lived in the neighborhood of Faculteta on Sredna Gora Street. There were over 100 Romani-Jewish families in Sofia. Following the Holocaust, most left for Israel, but several families stayed in Bulgaria.[16]
