Looking for immigrants from Sweden 1881-1885

Hi,

this is my fist visit in this forum so I hope that's OK to post a question. I have been working with Swedish genealogy during 20 years but have very little knowledge about genealogy in US.

I am searching information about three realitves to me (se below).
They emigrated from Sweden to US between 1881 and 1885.
I can't found any information about them in CasteGardens database.

I hope someone can give any information about where I can go on with my research.
Thanks in advance.

Best Regards / Ingvar
