[Ger-Poland-Volhynia] TIEFENBACH Research (back again)

[PHUEV at aol.com]

Hello to All
 
My name is Eveline Tiefenbach (Walsh), I have ben on this list  before.
 
I am still in the search of the family TIEFENBACH after 1939 that  immigrated 
from Vohlynia to Posen, been having though not very much luck.
 
A couple of weeks ago, I have recieved my father in law Wilhelm (Willi)  
TIEFENBACH Feldpost from 1944 from HOK that had never reached his family when he  
was a POW in the USA.
 
Hermann Tiefenbach
Kleindorf
6 Gostingen-Kr.Ostrowo/Wartheland
 
and
 
Kleindorf
6 Neu Skalden-Kr.Ostrowo
 
is anyone researching in this area?
 
He had also mentioned the names in his letter:
 
Frida HEUSCHEL, in the letter he wrote part of the Household ??, have no  
clue for this meaning
 
And these were his freinds:
 
Adam KOWALEWITSCH
Willi MATTES or MATTER (hard to read)
Ruddi SCHNERCH
 
Is anyone researching these names that might can help out, who these person  
are?
 
Wishing you all a great day.
My regards,
Eveline Tiefenbach
