My grandfather, Konstantin Georgiev, was born in Bulgaria on Jan. 14, 1990 then detained in a labor camp from 1944 to about 1961, when he escaped and moved to the U.S. In Bulgaria, Kons had 2 brothers and was involved in various business enterprises (rose oil production, alcohol production, real estate). He was married to Penka Dustabanov in 1923. Penka was related to Tsanko Dustabanov, a revolutionary and freedom fighter. I'm looking for any additional information about them or their families.
