Meaning or purpose of second last names

[Nancy Jaderen]

In my research I have come across several ancestors who have added a second last name.Do they denote occupations,titles or have any other special meaning?They are:Skomaker,Bergsman,Namdeman,Herssing and Hellstrom.
Thank you

Nancy,
 
in this case you have both ocupations and  surnamnes.
skomaker=shoemaker
bergsman=mountain man, miner and iron maker
Naemdeman=jury man
Hersing and Hellstrom are taken last names, often preceded by a patronym, eg Andersson, ie the son of Anders

[Elisabeth Thorsell]

I would rather translate bergsman with mining farmer or mine part owner, as he owned a share in a mine, but also farmed.

[Stig Geber]

Elisabeth is right in her explanation but the bergsman often also was a part owner in a blast furnace which was used by the owners in a sequence during the season.
