Marriage Register Lookup

Could someone with access to the Schubert books please do a
lookup for me. I have the following data from the LDS microfilms:

1. Aug 6 or 16, 1790 -

born to Christian Viktor HARMS and Sophia Barbara (geb.
HARMSEN) a son, Christian Friedrich Ulrich HARMS either in
GREESE or KRITZOW (Kirchspiel L�bow).

2. Apr 9 1825 -

born to Friedrich Ulrich HARMS and Maria (geb. Witthohn) a son,
Christopher Victor Friedrich HARMS in GREESE (Kirchspiel
L�bow).

I cannot find a record of the marriage between Friedrich Ulrich
HARMS and Maria Witthohn. I assume that it took place in
KRITZOW or GREESE.

Any help would be greatly appreciated.

Thank You,
