Rob, I, too, have no idea, but just to clarify: Do you want to know how many couples had married before in the same year or in general (since the formation of the county in 1821)?
Laurie, wasn't there also a cholera epidemic with a high death toll (especially amongst slaves) in the first half of the 19th century that (besides tuberculosis) inspired Poe to write "The mask of the read death"?
