[Ger-Poland-Volhynia] Two towns in Volhynia

[Christopher Menke]

Hello All,
  Were there two towns in the same vicinity as Alexandria and Mariendorf (Puchawa) Volhynia called Kostsche and Janowka? My Menke / Manke family was from Alexandria / Mariendorf, and there were Menke's in Kostsche and Janowka. 
  Tomorrow I am making my first visit to an LDS center to order films. 
  Thanks, Chris Menke
