Yes, the Lewis Adair that I was looking for had a son named Lebious Lawrence Adair born June 30, 1850 in Pennsylvania and died April 28, 1940 in Ogle Co., Il. Lewis Adair is my great-great grandfather. I am descended from his first wife Lavina Klingensmith. Since I posted this in 2001, I have found quite a bit about him. Is he related to you?
