My great great grandparents

Hello my name is Andreas and im into ancestry research and finding out more information on what people i come from and were my Origin starts. Ive been doing this work since 2014/15 , and i have inherited lots of great photographs and stories i would love to share with you all.
My family is as far i as i can trace them, trough records scandinavian. In my roots i found lots of military service and a handfull of famous Norwegians.I was suprised when i found out that my great great grandfather Johannes Sundvor(born 1871) was the man that wrote down and helped saving a whole lifelong history of drummer heritage in Norway. He travelled across norway meeting and writing down all drummer songs( both military and wedding ones) he could find from the living eyewitnesses. He also worked as a police officer and author. Then there is Eirik sundvor(Born 1902) who was a famous photographer and who was on the mission in 1944 Arne Dahl military expedition to liberated Finnmark to help the Sovjets and Norwegians trace enemy movements and deliver importan documents and messages to the british and Norwegian gouverment in London.
