Judson, I have your Lee J. Smith in my records as half brother to my gg grandmother Mollie Margaret Smith who married William W. Wright. Their father was Robert Powell Smith. Mollie was a daughter by Robert's first marriage to Cornelia Luck, and Lee was his son by his second marriage. Mollie and W. Wright are also buried at County Line.
I can get you more information if you're interested. Assuming you are a descendant of Lee, I was wondering if you could tell me about the old family homestead and cemetery, known as "River Hill" somewhere on the North Anna near Chilesburg. According to information I have, it was passed down from Lee Smith to the Madeline Smith & A.B. Driver you mentioned in your post. I was interested in trying to locate it and perhaps see the cemetery if it's still there.
p.s. - I'll cross post to your e-mail just in case.
