Georg Elfvengren
Colonel Georg (Yrjö) Elfvengren (8 September 1889, Sortavala – 10 June 1927, Moscow) was a Finnish officer of the Russian Imperial Guard during the First World War and a noted commander of the Finnish Civil War and Heimosodat, who sympathized with the Russian White movement and fought against Finnish and Russian Red Guards on the Karelian Isthmus on both sides of the Finland-Russia border. From November 1919 to May 1920 he was the chairman of the governing council of the Republic of North Ingria. Presumably an ethnic Belarusian from his mother's side, for some period he has also served as a diplomat for the Belarusian Democratic Republic in Finland. He was executed by shooting in Moscow in 1927. References
