[Ger-Poland-Volhynia] Markowo, Siarczyce, and Biernatki BMD records

[ra_stein at telus.net]

The German settlements Markowo, Siarczyce, and Biernatki were located about 15 km southwest of Wloclawek, Poland.  I am looking for BMD church records for the period prior to 1808 and suspect they may be in one of the nearby Catholic parishes, namely  Kruszyn, Brzesc Kujawski, Luraniec, or Wloclawek.  Records of all these parishes are on LDS microfilms.   Does anyone know which parish is most likely to have the German records from these villages?
