Pedersen/Hammer

I’m looking for the ship manifests for this family. I know most, if not all of them, were in the 1875 Norway Census and some of them started showing up in the US Census in 1880 or later. The US Census data shows they probably came to the US between 1878 and 1881.

After arriving in the US, the surname became Hammer and some of the first names appear “Americanized”.
