Genealogy / Czappa / Klein - Kashubian name / Putzig, Puck Poland? [8]

My father's family came to the USA from West Prussia, specifically what was Putzig, now Puck Poland. The name was originally spelled Czappa. I have seen it also spelled Czap. The name was Americanized to Chapp. The family settled in Detroit in 1872 just after the Franco-Prussian War.

Can any one provide direction to find any data on this location and records from there? Any recognition of the Czappa surname? My grandmother said her father-in-law spoke Kashubian and German.
