Never mind, I just discovered the "Records Search" portion of Family Search, don't know how I missed that one, thank you! Now, just to see if I can somehow get my hands on some images of the original records. In particular, the marriage certificate of Anna and John T.
That marriage record of John T. and Anna Bennett is definitely them, but I have no idea why it lists the bride's name as Mary G. Moore! It did give me a marriage date that I had been looking for. Other than the census records I have with Anna Bennett (m. O'Bryant) in them (all except 1900), this is one of earliest pieces of information I have on Anna's life.
