Germans from Russia Heritage Society
A large U.S. organization originally focused on Germans from Russia who settled in the Dakotas. GRHS is now the best resource for Germans from Russia information I know of. GRHS once focused on the heritage of Germans from Russia (Folklore, recipes, stories, songs, history, etc) but genealogy has become a huge part of the services they provide to the public and their members. GRHS is actively purchasing newly accessible records from the Russia archives and publishing indexes on their website. A yearly GRHS membership is a great investment if you had family in Russia as much of the data available on the GRHS website is available to members only. My direct family line spent 30 years in this Russia and left only Emilie Gauer behind when they came to Canada in 1890.
