I just came across this thread (11/19/2018), and learned that you have researched the Old Military Road. I grew up in Greenville and want to locate exactly where the road was. I am a retired American History HS and junior college teacher and would like to contribute time in helping you locate the road, if you are still researching it. I now live in Bourbon, MO, a 2 1/2 hour drive from Greenville, but would willingly contribute time and cover my own expenses in aiding your work. I would like to discuss this possibility with you.
Please contact me outside this thread at: firstname.lastname@example.org. My landline phone is (573) 732-4710. You would need to leave a message because we screen our calls. Be sure to say what you're calling about. I'll pick up if I'm in the house, or will call you back ASAP.
Hoping to hear from you,
