novice researcher needs PINNE surname help #germany

Helen <helen@...>

I am trying to locate any information relating to the surname of PINNE.
I know there is a town in Posen called PINNE, but my great grandfather,
Heinrich August Friedrich Ludwig (August)PINNE and his wife, Johanne
Henriette Juliane (Auguste) LIES, emigrated to Australia >from Hamburg in
1853. My great, great grandfather was Johann Heinrich PINNE but I have
no information on him or his wife Sophie Wilhelmine PFENG.
Does the PINNE surname come >from the township? If so when approximately
would this have happened? Any help would be greatly appreciated.
