FASCH, additional information

I now have some additional information about my FASCH ancestors. There is a small correction in my great-grandmother's name. It is: Johanna Wilhelmine Henriette FASCH. One of the baptismal records for her children lists her father as:
Heinrich Conrad Theodor FASCH.
Other family members listed, but relationships not shown, were: Wilhelm Heinrich Carl FASCH and Wilhelmine Dorothee Louise FASCH.
There was a Heinrich Conrad Theodor FASCH born in Oldenburg in 1784. His wife was Catharine Charlotte Mueller, born in 1781 in Oldenburg. I don't know if this is the right family. Does anyone have access to the Oldenburg OSB and would check this out for me?
Your help will be greatly appreciated.
