Kopischke Family

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.

are they Polish? all names sound German.

KOPISCHKE: German respelling of Kopiszka (Old Polish for digger). Most names ending in -ke are Germanised versions of Polish or other Slavonic names ending in -ka. For instance, Lipke is meaningless in German, because it comes from Polish or Czech lipka (little linden or lime tree). In Poland the Kopischke name exists but Kopiszka is far more common.

HAUFF: a German surname probably derived from the German word for heap (same Germanic root incidentally, pile, mound or hoard.
