Hi Reina, Hi John,
Donkvitz seems to have been just a farm (a steading?) on the island of
Rügen. I don't know, if anything is left from this place. Our genealogical
place database shows Donkvitz - see

I believe, the church where your ancestors were baptized, is Samtens. Can
anybody say anything about the church books / records of Samtens?
Greetings from Berlin
