I realize it has been a few years since you posted this message but thought I would take a chance.
In your Loehr book do you have any marriages to a Carter in Shenandoah County,Virginia around 25 Dec 1796?
We have a Mary Lehr/Lohr (pick a spelling) that marries a John Carter in Shenandoah. No one signed their marriage bond and they seem to have sprung from the earth or as my cousin commments there were aliens with no known earth relatives.
Thank you in advance for any light you might shed on these people. Norene
