Pia, the translator said it should be typed "förman" instead of "förnam" in the Swedish text, should we edit this word, as the requester probably did a mistake when he typed this text?
There are many misspellings here, vague source text! I don't know if it should be typed "förman", but it could be! When looking at the meaning of "Jarl" (wiki) it says chief, chieftain ...and "förman" is the same as "foreman or supervisor", so my guess is that you are right about it.
