Hi Bobby,
Depending on what you are actually looking for regarding Gross Elbe /
Klein Elbe.....
...the LDS has a so-called "Ortsfamilienbuch" (Family lineage book) for
Gross Elbe and Klein Elbe available.
Author: Friedrich-Karl Krentel
Call no. is: 943 B4do ser. B v. 241
It covers the time period from 1709 to 1875 and also contains
information regarding the homes / farms and their owners in Gross Elbe
and Klein Elbe.
You can easily get this on lease at your nearby LDS center.
Hope that helps.
Best wishes,
Vera Nagel
