The MOGenWeb county sites were flooded with queries in their early days. Later, the mailing lists and message boards at Genforum.com and Rootsweb.com were used extensively for this purpose. Now, Genforum.com no longer accepts new posts, and the Rootsweb mailing list servers haven't worked properly for quite some time. For that reason, I've created mailing lists for researchers to use if they so desire. The Pettis County mailing list is located at Google Groups. You can also submit your query to Kris.
