Ofb Himbergen book- Dubbekolt und Botze [umlauts there.]

In this book by Porth and Freisch are some village names. Dubbekolt
   and Botze. With umlauts.

   Would anyone on the board think that this could be Duebbekold and
   Boitze? Sometimes Vindorf is Findorf in old works.

   I hope some one knows.

   have a good day
