Apparently Viker parish didn't exist in 1855 and Johannes was born in Nora / Nora Bergs parish. I found his birth date of 24 Jun 1855 in the "Sweden, Household Examination Books, 1880-1930" database on Familysearch.org. Here's his birth record, he's the last record on the page, # 124. ArkivDigital would have a much better copy.https://sok.riksarkivet.se/bildvisning/C0001563_00184#?c=&am...
Here's the family in the 1900 Swedish Census (if this page doesn't load, go to: https://sok.riksarkivet.se/folkrakningar
and type in johannes dahl 1855 and it will come up).https://sok.riksarkivet.se/folkrakningar?Fornamn=johannes&am...
