names of ships

Syvert Munsen and Mesine Alette Berntdanielsdatter (from Bergen) and their children Elisabeth (born in Haugesund), Daniel, and Martin immigrated to USA by way of Quebec in 1864. Trying to locate name of ship? Johannes Nilssen born 1843 near Bergen (parents Gjetlaug Espendtr. and Neils Johannessen) immigrated by himself in 1860 or 1861 to Iowa possibly Decorah IA. Arrived, I was told, in New York but it seems most other Norweigians went to Quebec? Name of ship? Thanks Edited by - lqhs
