step daughter Emma Sofia Pettersdotter (She was the daughter of Peter Larsson, you said, so she was Peter's daughter and not the daughter of a Lars.), born 28 June 1851, moved to page 81 in 1867
(ditto for step???) son Peter Gustaf Pettersson, born 5 November 1855, moved to page 81 in 1868.
All of that family were born in Bjurtkärn??? I wonder if that is an old spelling of Bjurtjärn parish.
Page 81 is on this Genline page.
GID # 464.40.34700
Peter Gustaf Pettersson is listed as a foster son and Emma Sofia Pettersdotter is listed as a piga (maid) on this page. Several lines up I see the widowed mother (but whose mother? Perhaps she is connected to the family at the top of the page, but I don't have time to type their names and check on them. All of those were from Bjurtkärn, wherever that might be.) Stina Larsdotter, born 6 February 1802 in Bjurtkärn, followed by Brother? (and something else) Peter Linnarsson, born 20 January 1845 in Bjurtkärn.
At any rate, this Peter Gustaf Petersson died 4 February 1869 (NOT 1969). Emma Sofia Pettersdotter went to North America 25? April 1869, certificate number 24.
Pettersdotter, Emma Sofia Piga = maid. (unmarried woman)
Emigrated 4/23/1869 from Kväggestorp, Bjurtjärn, Värmlands län (Värmland) to Nordamerika

The Emihamn database started about 1869. Emihamn was made from registrations with Swedish port police before leaving Sweden. (Not all Swedes left through a Swedish port.) The others left one year too soon but here is Emma.
