[Ger-Poland-Volhynia] Location Debina

[Dr. Frank Stewner]

I have two questions concerning locations:
1. Can it be that all these names are describing one and the same location: Debina, Debine, Debiny, Debiny Hol., Dembin, Denbina, Dembine, Hauland Dembina, Hauland Dembine, Hol. Dembina and Hol. Dembine? Is that village now-a-days called Debina and has the coordinates 521728N and 185427E?
2.  I cannot find Eichhauland or Eichholland anywhere. Can it be that those two are also names for Debina?
