at first glance I could not find a Strossdorf, but some info on Pyritz.
Pyritz is in district of Stettin, Pommerania, Poland.
Well, just found out about Strossdorf. The name used to be Strohsdorf = Strozewo today, in Poland.
Pyritz is called Powiat pyrzycki today.http://de.wikipedia.org/wiki/Gmina_Pyrzyce
there is a databas in Englisch. Some Ohms in Pyritz are listed there. The database is in English and German:http://en.pommerndatenbank.de/index.html?sessid=1ec0183babcf...
Here are the places incorporated or quite close to Pyrick:http://wiki-de.genealogy.net/Kreis_Pyritz
Here are some address books of Pyritz:http://wiki-de.genealogy.net/Kategorie:Adressbuch_f%C3%BCr_P...
You'd better post on the Polish board.
Hope this helps.
