Brevik - Telemark research

Hello I have found (also have a hard copy of the documents from my mother) online what I believe to be my grandfather, Henry Marinius Hansens baptismal record DOB 18 JUL 1889, bapt . http://www.arkivverket.no/URN:kb_read?show=40&uid=8513&urnread_imagesize=big&hode=nei&ls=1 Also, what are the headings saying under each section? every translator I have found is of the new norwegian language. My mother believed his parents names to be Janna Elise Ingebretsen DOB 23 OCT 1862 and Lars Peder Hansen DOB 21 NOV 1860 - this seems to bear out on the record (if correct, it looks as though they were married just a few weeks before my GF was born 2 JUL 1889) . But I do not know how to understand the other information on the record (I do get birthdate and bapt date) and he passed sadly when she was just 12yrs old, so there is no way - or anyone else - to find other other living relatives until we can figure this out. She thinks he had a brother and a sister (I may have found them going through the same baptismal records Ingerid Marie 1891, Borghild 1893, Ernst Leonard 1896, Hjordis 1898, Lilly Julie 1900) and that she thinks she remembers her parents going to Canada to visit with an uncle and his wife when she was just a young girl. Where they would be, how to find them, no idea. But I would like to try before my mother passes away and she is now 83yrs old and any of her cousins and maybe their children, they may have photos. When my GF came to US, for some reason he became written as Hanson - army records and his death - probably due to his army records. They were never corrected and were told they could not be even with the baptismal record (which is why my mother got a copy of it years ago) - no mistake, his wife and children were all Hansen. I have been told there is another record in regards to the baptism record but have not been able to find it, and on there, it suggests to the names of Janna - his mother - parents names. I guess I wondered if that would have been godparents listed (the link above may be that record actually). Any help appreciated! until I can fully understand this, I cannot try to find his family, which surely must still be in the area. Someone told me that he would have had another name in Norway - his 'place he came from name' - but no idea what that would be either, than wondered if that was the word before Lars Peter on the record - Styrmand?.
