*Johan’s genealogical study #3*

Hello, I’ve had many unresolved mysteries and brick walls in certain people that form part of my Norwegian ancestry. I need help finding more information about people in my tree. MYSTERIES: • Ole Nielsen Øhrn was born in Kongsberg on January 7th, 1820. I know that his family was from Kongsberg but I’d like to know more about his family, in terms of their story, and delve deeper into their professions (probably working on farms, I suppose). • I know that the name Øhrn originated from a farm but where exactly is it located? Are there some pictures of it that I could find online (google maps, for example)? • I heard of a supposed German ancestry in Kongsberg because of the miners that were brought into the silver mines in the 16th and 17th centuries. Thank you to anyone who at least stops by for some advice or some well-needed help.
