[Ger-Poland-Volhynia] Where is Szenwald, Rypin?

[Earl.Schultz]

The village of Szenwald or Szynwald appears fairly frequently in the
Michalki, Rypin parish records.  However, I have been unable to find it on
any map including our usual on-line maps.  If it exists in the Michalki
parish it should be about 30 miles NNW of Plock, in the Rypin area.  Does
anyone know where this village could be.  

Thanks,
Earl Schultz
