Hi again Bonita,
My RIECKMANNs and WOLLEs and their godparents were in Ebstorf, Linden,
Altenebstorf, Wittenwater, and Oerrel. You have the same towns, but all
different surnames. Apparently, though, some WOLLEs (in the US) married
SCHROEDER. My aunt remembers that some relatives of her mother (Anna
RIECKMANN MUELLER) named SCHROEDER lived at Peoria, IL, and came to visit
in Nebraska.
Where/How did you get your information? The church records have not been
microfilmed by LDS. Did you hire a researcher? Go to Uelzen? Have
awesome family records? I'm looking for clues to finding more info. 
Thanks!
Mona
