Karl Andersen - Ship Master from Grimstad/Froland

I am search of any information on my Great Grandfather Karl Andersen. Per some family records, it states that he was a ship master. Unfortunatly, I do not have a date to when he came to the US, however I believe it to be in the 1880's. He is from the Grimstad/Froland area. He had a wife by the name of Hanna. He had a brother named Kittel Andersen b 1841, brother named Schjelluf Andersen born 1843 and a sister named Maren. The Farm name was Hurv. If any one has any information, please email me. Thank you in advance. Bob Anderson Robert Anderson
