[Ger-Poland-Volhynia] Village today in Poland

[GVLESS at aol.com]

I am looking for information that says there may be German records existing  
for a village that once was considered a German one but now is in today's  
Poland.  My father's parents immigrated to the U.S. in 1890 from what was  known 
as Reetz, Arnswalde, Brandenburg.  I understand that after WWII the  village 
and other areas in this part of Germany was given to Poland.  How  would one 
find out if any records exist for this former German village?   Just thought 
some of you Germans on this list might provide a clue for me in  order to do 
further research.  Someone has told me this particular area was  known as the 
Neumark area and have tried the Internet for something about this  but no luck on 
how and where to check for records - if they still exist.   My grandparents 
had been in correspondence with family members through the  1930's but contact 
was lost during WWII.  Since then no one alive today in  the States (like me) 
knows any more of the family.  Names were Krahmer and  Fradrich.  It is 
conceivable that anyone that even survived WWII may have  migrated out into Germany 
itself somewhere.  But there had been no  indication of any of those relatives 
still around.  I know this does not  refer to a migration to Volhynia!  But 
just thought someone might have a  clue about records for the former Neumark 
area of Germany.
