 So I've come to a high-rise apartment block in Georgia's capital, Tbilisi, and I'm here to speak to Levan Pesvianitse about his family's history. His grandfather, Viktor, and uncle, Georgi, were both executed without trial during Stalin's Great Terror of 1937-1938, which targeted tens of thousands of Georgians. But Levan's only recently been finding out more about what happened to them.
