Thanks again for the tips. I have a copy of the Tazewell county history in the mail now, but expect each answered question to raise several news ones in its' place. If you, or anyone, should know of any other local resources, such as surviving newspaper archives(assumming grandpa didn't burn them all), that would be greatly appreciated as well.
Best regards, Chuck
P.S. The county roads you mentioned do show on google earth satelite photos.
