We have just found the marriage record for MRS Sally Belcher to a William Freeman in 1821. Forgive me but I am not familiar Amelia County Records.
You say that you have a copy of their marriage bond and conscent form. Where are these held? Are they on microfilm, courthouse, or archives/historical society??
We believe that Sally's maiden name was Fleming. Have you seen a record for a marriage of a Sally/Sarah Fleming to a Belcher prior to 1821. We also believe that she was born around 1790 [based on later census].

Thank you,
Pattie
