TIL Kara-Murza
"[Kara-Murza's] father is a great-grandson of Latvian revolutionary Voldemārs Bissenieks (1884–1938), and great-grand-nephew of Latvia's first Ambassador to Great Britain, Georgs Bissenieks (1885–1941), both of whom were shot by the NKVD. The Latvian agronomist and publisher Jānis Bissenieks (1864–1923) was their older brother."
