Carl Andersen

I had put out a posting last year, but now have some additional information about my Great Grandfather Carl Andersen. Family word of mouth had him as a sea captain, but believe him to be some type of seaman. Carl was born in Aust Agder - froland area in 1856. He had 2 older brothers Kittel and Schelluf and a sister Maren. He emigrated to the US in 1888 and became a citizen of the US in 1893 living in Elizabeth Port, New Jersey. He died in 1930. I was recently looking at some old family photos in which my Great Grandmother (hanna or johanna) was in one photo done by Brom, Barnes and Bell in Liverpool (Photograhers to the Queen). . Then I have another photo of her done by Alexander Asnon in Elizabeth, New Jersey....and she looks the same - so timing of when the photos were taken are not far apart (so would have to be around 1888 or so). Problem is I don't know much about my Great Grandmother as I am even guessing what her name was... I have found some ship registers that show a Carl Andersen on the Le Louisiana in 1881 out of Hampshire Southampton....but that is about it. Is there a way to find any records that could tie him to england/his wifes maiden name, or how they made it to the US? Any help would be appreciated. Regards, Bob Anderson
