Unable to find ancestors Berit, Tonette, Marit Lee

I've searched every single combination of each of the names I have and have been unsuccessful. Any help is appreciated!! According to US records Berit, Tonette and Marit Lee arrived in the U.S. in 1867. Berit was around 30, Tonette, 4 and Marit an infant. I am very interested in any more info on Berit and even more so, who the father of Tonette and Marit was, and if he traveled with them.
