Jakob and Mathea Anderson - Info needed

Jakob Anderson born May 5, 1836 - Hole, Hurumeie, Norway Marta M Larsdatter born June 11, 1846 - Kirkerrud, Norway Married May 21, 1866 Sylling Church, Sylling Norway Jakob's father was Anders Johannessen - Hole, Hurumeie. Not sure when he was born or who his parents would be. Jakob's mother was Mari Johnsdatter - Hurum Farms, born in 1792?? No further information about her. Jakob was illegitimate, so I do not know if his parents Anders and Mari ever were married to each other or if they married other people. I do not know if there are siblings to Jakob. Looking for any information related to my family. Marta was the daughter of Lars Evensen (1818) and Kirsti Andersdatter 1823. Kirsti's parents were Anders Gulbranden and Mari Jakobsdatter. I do not have farm name's or dates. Jakob and Marta came to Leer Michigan some time in 1872. I would like to find the name of the ship and if other family member beside their children came with them. I have been on the digitalarkivet web site and found a few records. English-Norwegian dictionary only gets you so far and is very time consuming, but I am still learning.
