Here's a listing of Bibb County churches and historical materials available.Although this is from Mercer Univ page...you'll see the microfilm is available sometimes through LDS and GDAH.
I would guess that Washington Memorial Library might also have it.
Please, if anyone does look at these films, would you try to write up a brief history of the church, and transcribe whatever membership lists you might have the time to do.
CB means Church Record book.....the other abbreviations can be found at the top of the page on the above link.
