Genealogy / THE MEANING AND RESEARCH OF MY POLISH LAST NAME, SURNAME? [4500]

Would like to know what the meaning of one of my family names is.
KUPSCH.... I have been looking for my great grandfather, Johann Freidrich
Kupsch, born in Klein Blumberg, Crossen Prussia, which I believe is part
of Poland back then, he was born in 1835approximately, left Hamburg for
Tasmania, Australia in 1870, once he arrived in Tasmania, he never left.
Would love to find a family connection, as all of his records were destroyed
in world war 2, so I cannot trace my great grandfather or his family.
Can anyone please please help..........
