Elsa Gudrun Olsen

Now being Dec 8, 2021 I have a new hint that perhaps solves a mystery as to why Elsa Gudrun Hermansen was born after the supposed death date of her supposed father (Hjalmar Hermansen) who supposedly died in 1912 which is three years before Elsa's DOB in 1915.
The mystery may be solved by the birth and baptism church record which does not list Hjalmar as the father of Elsa. The record lists Karl Gusby Bodil of Goteborg as the father. The mother appears to list the Agnes Azora Fredriksen known to me as the mother of Elsa.
The mystery of how Hjalmar could be the father (and now thought not to be due to the birth/baptism record) has plagued me for over 10 years.
