Info on Hegg & Hagelie Surnames

I am searching for some information regarding two sets of ancestors from Norway. HEGG: My great grandmother Inga was born on a ship to Buffalo, NY from Norway on Dec 21, 1882. Her mother (unknown) died on the ship during childbirth. Her father was Louis Torgerson Hegg born 6/17/1858 in Ullensaker, Akershus, Norway. Louis also had a brother Ole who adopted Inga once in the US. I would like to know the name of Louis's wife and possilby a marriage record and ship record so I know what ship she died on. Also, I am looking for immigration, birth, and death information for a Halvor H. Hagelie, born in Hjelmeland, Norway and his wife Liva, born in Hatedervedt, Stavanger, Norway. His first known son, Christ, was born in 1847 in Ossian, IA, which mean immigration was prior to that year.
