Hello Marcin,
The script is difficult for me since the page you send is in another
language. Perhaps it is in some eastern European script? However, the
register is likely German. However, I can see the Johann, but certainly
would have no idea what the surname is. So I would say it is hard to know
what that town would be. I have a really good atlas of Germany. There is a
tiny place called Clausmoor. Do you have any interest in pursuing the
history of the area? The LDS has a lot of information about the Gifhorn
area. An example is this:
Court records of an account of hearths, horses, manors, estates, populace,
buildings, house taxes, inhabitants, homes, animals, blind, and deaf of the
court of Gifhorn, Hannover. Includes Abbesbüttel, Dalldorf, Didderse,
Eickhorst, Ettenbüttel, Harzbüttel, Hillerse, Lagesbüttel, Leiferde,
Wasbüttel, Walle, Winkel, Rötgesbüttel, Wahrenholz, Dannenbüttel, Dragen,
Gamsen, Gilde, Krümme, Neubockel, Neudorf, Platendorf, Stüde, Triangel,
Westerbeck, Wilsche, Allenbüttel, Allerbüttel, Bechtsbüttel, Brunsbüttel,

go to Place and then write in Gifhorn.
Good luck,
