Samson Nilsen Helland

Can anyone help me find an arrival record to the US for Samson Nilsen Helland? He is listed as "Simson" in the 1900 census in Red Lake, MN, living with his son Nils (Nels) Bertinius Helland, and the year of his immigration is listed as1898. Samson was born Samson Nilsen Slogvig in 1834 in Tysvær, but moved to Sand, Rogaland, in 1861. He married Ambjørg Tormodsdotter Helland, and after his marriage, the family used her surname. Ambjørg was apparently dead when Samson emigrated. Unfortunately, I haven't been able to find her death in church records. Thanks for any help!
