Hi Judith!
Here is some info I have found on SVAR (Swedish Archives), and in the Swedish Church records on Genline.
First of all, Erik was born Aug 17 1855 in Gustaf Adolf Parish in Värmland, his birth record can be found at C:5, Födde, 1844-1861, Upplund (torp), Gustaf Adolf Parish, Värmland, Genline GID: 489.26.63000, page 67. He married Lisa Katrina (Cajsa) Ersdotter born Mar 16 1858 in Tyngsjö, Kopparbergs län, they were married Mar 25 1879 in Gökberget, Tyngsjö, Kopparbergs län, their marriage record can be found in the Swedish Archives Records, _scb Kopparberg, :672, Födde, Vigsel, Död, 1879-1879, Genline GID: 100020.21.64800. Erik and Lisa and their first child Olof Theodor born Sept 10 1880 in Gökberget, Tyngsjö, Kopparbergs län, can be found at AI:3, HFL, 1875-1884, Gökberget, Tyngsjö, Kopparbergs län, page 149, GID: 147.9.46400.
I found Erik's parents and siblings in the Clerical Survey Records on Genline at A:9, HFL, 1855-1860, Upplund, Gustaf Adolf, Värmland, Page 121. His parents were Olof Olsson born Jan 6 1819 in Gustaf Adolf, Värmland and Carin Persdotter born Nov 9 1819 in Gustaf Adolf, Värmland.
Hope this info will be of some use for you!
Have a nice day!
