Hi! I have added links and references to Swedish Church records to this profile indicating that the father currently linked to Charles Hjalmar is incorrect. See also the references on the profile for the current father. The mothers name is correct but her patronymicon indicates that there are further errors in the tree. Johanna Persdotter was most likely not a child of a man named Gustaf.
Charles Hjalmar and his mother Johanna Persdotter should be separated from Per (Peter) Erik Olsson.
