Kloppenburg Familie und von Minden familie

Hello List Members:
I am seeking information on two women from the mid 1700s, so perhaps that is too early, however I thought I would try.
- Anna von Minden born about 1757, perhaps in Neudtadt bei Overgoenne. She married Gerd Willers, the younger (I don't know where) and they had a son named Oltmann Willers in 1790 (I do not know where).
I'd like to know her parents, when she married, and when and where she died.
- Anna Margarete Kloppenburg born around 1760, perhaps in Eckern bei Zwischenhahn. She married Lueder Bohemann (I don't know where) and they had a daughter named Thalke Margarethe Bohemann in Eckern in September 1784.
I'd like to know her parents, when she married, and when and where she died.
If possible, I would like very much to know of a local genealogist who may do research for hire. I was in the Oldenburg archives last week, but had too little time to study the records.
Vielen Dank fuer Ihre Hilfe!
