Genealogy / Ellis Island or something else to find about my grandparents? [4]

I have gone thru Ancestry.com trying to find out where my grandparents landed and I cannot find any mention of them in any of the ship logs or where they landed. Where else would I look?

Genealogy / Kopischke Family [3]

My grandfather was born in Chicago as Arthur Charles Kopischke. His parents were Hermann Kopischke and Bertha Hauff. He had an older brother George Kopischke. Hermann died in 1897. Bertha remarred a Peter Heinz and had 4 more children. I am trying to find famioy of Hermann. He did come to the US as a minor. I do not know who his parents or siblings were. Any help would be great.
