Searching for Family from sweden

Hello: I am searching for information on my family that emmigrated from Sweden, and am unsure if they went through Norway or not... The name is Aron (aaron) Krans - He emigrated from Sweden in 1881 Born in 1837. My grandfather tells me he emigrated from a town called Hangsdahl...I don't know of a town in Sweden with that name, so I thought maybe it was the port he came over from. He died in 1915. He had a son named Gustaf and a daughter named Hulda.... I have all the records on the other side of my family, but am really looking for these folks. Thank you for nay help
