[Ger-Poland-Volhynia] FEIFERT / STIEBNER in Polen

[Ohgrmtns at aol.com]

I have been searching for any possible information on my grandparents,  
HEINRICH FEIFERT and KAROLINE FEIFERT (geb. STIEBNER). What I have been able to  
learn has been 2nd-hand through the EWZ on my great aunt, OTTILIE FEIFERT (geb.  
LAU). The information there stated that both HEINRICH and KAROLINE were born 
in  Polen in 1847 and 1849 respectively. Can anyone provide me with direction 
on how  and where I might be able to gather further information?
 
Additionally, I have been searching for information on my great uncle, EMIL  
FEIFERT. Again, through information on OTTILIE FEIFERT (geb. LAU) on the EWZ, 
it  was stated that he was born in Krownau (sp?), Kreis Warschau (?). From the 
 information I have gathered, his birth there could be possible. However, in  
researching that area, I have been unable to locate Krownau. Can anyone 
provide  me with some guidance here?
 
Thanks,
Kristen FEIFERT Clark
