Johannes Ole Selseng

i am trying to find the birth of Johanne Ole Selseng. The information that I have seen is that he is the son of Ole Pedersen Selseng and Ragnild Tostendatter Alme. Supposedly he was born in Sogndal 1 Jan 1836. I can't find anything in the archives to support this. The information I saw came from other family trees. I look at this but try to find the actual records. I believe Ole and Ragnild came to America in 1844 but the emigration records seem to be a bit confusing. They came with several children but I don't think Johanne was one of them. In 1844 he would have been quite youg. I think the vessel was the Ørnen. If anyone can take a look at this, I would greatly appreciate it. Thank you.
