Missing Emigrant family of Twelve

Ole Gulbrandsen and his family are shown in church records as "utflyttar" in 1852. No destination is shown. I can't find them in later records so assume they may have emigrated to America. 1852 seems to be their only record anywhere. His son Anton, born 1849, is my main interest because I have an ancestor Anton, unknown surname, who was about the same age. He was orphaned about 1852-1853 and taken in by a family in Michigan. This all seems coincidental to the SS Atlantic shipwreck on Lake Erie. Ole Gulbrandsen is shown in this record: http://digitalarkivet.arkivverket.no/en-gb/kb/uf/hending/hu00000000014395 He is serial no.76, and I think his family ends with no.87. They were in Hedal, Sør-Aurdal. This seems to be in Valdres where many of the SS Atlantic victims were from. Their names don't appear to match with the list of victims, but this is something I have to know more about. I would appreciate any help anyone may have to offer. It has been a good experience to become acquainted with the necessary basics of the Norwegian language, and this is my first look at records not written in English. Takk (thanks?)
