I am trying to locate German Lutheran church records or civil records for Kreis Petrikau for the period 1840-1875. I am not sure where this region is. Is it in Volhynia or in what is now Poland? I can find a Petrikau  in Volhynia north of Zhitomir and east of Rovno. The family was living in Roszsischke parish by the 1880's.Is there a region called Kreis Petrikau further east, in Poland or the former East Prussia? Any leads would be much appreciated.
