Kurnik - Kornik

Kornik is a town in Western Poland, a few miles from Poznan. It's
famous for its castle, its arboretum, and its library.

While the word 'kurnik' means 'chicken coop' or 'hovel' in Polish, the
word 'kornik' translated from Polish means 'borer' or 'bark beetle' or
'woodworm' or 'sawyer'...

There's been an assumption that the Curnick and Cornick families in
England are the same family, with one group or other misspelling their
surname early on. However, if the Polish origin of the names is
correct, the different meaning of the two Polish words could suggest
two different family origins.
