I am writing in English as I can not speak neither Finnish or Russian (I am Estonian, living in Norway) and I hope other project members can come with suggestions.
My grandfather Viktor Mustonen/Viktor Tammur was born Viktor Mustonen in Pohi village in Ingria in 1931. His mother was Maria Mustonen, father Jaan/Juhan/Ivan Mustonen and sister Tüüne Mustonen.
Father died ca in 1945 in Vologoda, Viktor, Tüüne and mother Maria ended up in Estonia. First were Maria and Tüüne deported and later Viktor arrested for organizing an anti-government student organization (I have copies of some files in archive in Estonia, more in Victor's profile) and he got 8 years in prison, to Norilsk Gulag in 1949. I think Maria and Tüüne stayed in Russia, possibly emigrated to Finland after 1991, Viktor came back to Estonia, but I never met him.
I found a little announcement in the newspaper from 1942 where Katri Jakkimainen is looking for her sister Mari Mustonen, the father's name Viktor's birth certificate. Thus I assume Katri Jakkimainen is my great-grandaunt.
I appreciate any leads and suggestions on how to find documents and information on my relatives.
