Tracy, I couldn't find any of these people in the books I own. I did a bit of research on the internet and found them on Ancestry.com. I'm usre you've seen that information? Anyhow, I would suggest that you write to the county Courthouses and see if they can send you copies of these marriages.
James Ard and Dianna Price 8/22/1827 Pulaski Co William Price and Sally Owen 9/11/1800 Pulaski Co Cyrenus Ard and Telitha Flemming/Fleming/flening 8/17/1856 Wayne co. Elkin Fleming and Dorcas Vickers/Vickery 9/15/1833 Wayne Co. Martin McGuire and Feriba bartley 1865 Hickman, Tenn? George Bartley and Nancy Frazier 1826 maybe in Barren Co. or Monroe Co.
I'm not sure about Joseph Shaw and Martha. If they are connected to any of the above you might try in the same counties.

Hickman Co. http://www.rootsweb.com/~tnhickma/http://www.rootsweb.com/~tnhickma/ The Hickman Courthouse burned during the civil war and all records were lost. The genweb site (link above) has several volunters that might be able to help you in your search.
When you write the courthouses make you requests brief and clear and include a SASE so they can respond easily. I can also help you census searches if you need that. Let me know.
