Jens E. Markuson & Marn Andrina Brekke to NY 1870

I am looking for information on the ship on which Jens E. Markusen/Markuson and Marn Andrina "Maria" Brekke/Brakke came to NY in 1870. Jens E. Markusen and Marn Andrina Brekke sailed to New York from Maridalen, Christiana, Norway in 1870. They were united in marriage in New York and then traveled by train to locate in Greenfield Prairie, Minnesota, where he had a married brother. Kara D. (Kosmatka) Ishii
