I am trying to find the village that my 3rd great grandfather was born in.
This marriage document shows the village as Dubnik. I have used Shetl Seeker, Kartenmeister, and Meyers Gazateer to find this village. His brother
has records in the Nakel and Sadki area. I have searched those records to
no avail. I have searched in Dubnik, Slovakia and Dubnik=Sobidor also to
no avail. Those two villages are way too far away from where the brother
was found.

In the area of Sadki by Nakło kujawsko-pomorskie province there are villages Dębowo and Dąbki ???
