Can someone read this Letter Edged In Black please

Hi again, I was wondering if anyone could help me with this--in looking through Mom's stuff my sister and I found this letter edged in black written in either Swedish or Norwegian. I am not sure if anything will help me with the family on this but I was wondering if anyone could help me make out what it says and in which language it is as my grandmother came from Norway and grandfather came from Sweden. Grandfather went by John A. Anderson here in the US and grandmother went by Ingeborg (Inga) Nelson before she married grandfather. Please try to read as much as possible and I know I haven't done it correctly but it is as close as I could do with what I know. Thanks. (a long word I couldn't try to put down in English) gud i sitt clluisa rad vehagat hadankalb mih alskade make UNDANTAGSMANNEN ANDERS JOHAN NILSSON som stilla ailed SODRA RUNSTEN ONSDAGEN DEN 25 Dec 1912 i en alder af 71 ar 2 manader och 25 olager oli upt sarjd och saknad af mgh barn, barnbarn ocl broder samt slakt ocl vanner. Johanna Nilsson I know the above isn't done correctly but if something can be read from it I may know more as far as names. We thought it was from Grandma (maybe her father's death certificate or something?) but every name of Nilsson I look up is from Sweden so now am wondering if this is from Grandfather's side (he came from Sweden). I am hoping this will give us a clue as to the last name of one of them before they came to America. I am also hoping this can help find some other of the family over there (in either Sweden or Norway). Maybe this death notice will help find someone? Thanks for any help you can offer, Debra
