I am a descendant of Rebecca Adair born 1810 in Kentucky. She married William M. Morgan on 22 Sept 1835 in Clinton Co., Illinois. On the 1850 census they are living very close to a John Adair and a Mancel Adair. There is a John and a Mancel Adair in Trigg Co., Ky. in 1820 and a John Adair in Christian Co., Ky. in 1810. John and Mancel Adair moved to Clinton Co., Ill. in the 1820's or early 1830's as they do not appear on the 1830 census in Trigg or Christian Co. Ky. There is a Mancel Adair on the 1850 census for Waldran Co., Arkansas that gives his age as 58 born in South Carolina. I beleive my Rebecca is the daughter of John Adair.
