Gebowfske as spelled I have not. However, Gebowski or Glebowski yes. Look at
http://www.havers-family.co.uk/glebowski.html. As far as occupation common
to the region, look for a book titled "The Cassubian Civilization"
(Friedrich Lorentz). It has a great deal of information about the region
(circa 19th century).
"Albau Platzig"... My German is pretty bad. I'm sure others here will be
able to help much better than I can. This sounds more like the description
of a place than a name per se.
