His father was my great-great-great grandfather. His sister, Marie Brandt Nettum (married Ole Nettum) was my maternal grandpa's grandmother.
I have a "Family Chronicle" book that goes into some of the Trondheim childhood memories passed down to us. I'd LOVE to find more relatives out there - and like you, I'd like to find anything more I can on any more history in Norway.
Please contact me - thanks!
