Passenger list 1851 - bark Sjofna

looking for my great grand mother on a ships list. My grand father always said she came over in 1851 on the ship Sjofna. Her name was Mari Svensdatter/Svendsdatter Loeng. born 1831, Loeng farm Norway. I found this: Passenger list 1851 - bark Sjofna Captain Departure Arrival Source Søren A. Hovland Drammen May 31 New York July 21 Roll # 102, arr. no. 977 (passenger # 182) 182 Mari Loniedtr@Lornsdtr 20 f Between deck Loniedtter@Lornsdatter I am wondering if this could be a typo? I am thinking that this could be my gr grandmother Mari Loeng the age is correct. The name is very odd. What are your thoughts on this? Thank you for any help.
