I am missing a John W. [Wilkes] Alexander b. 1776 in Pennsylvania but moved to Iredell County, North Carolina in 1778 with his parents. By 1810 he was married and in Rutherford County, Tennessee. At that time he was enumerated with:
3 males under 10 years 1 male 26-45 years (himself) 2 females under 10 years 1 female 26-45 years
He was in the War of 1812 from TN and then he seems to have disappeared. Do you have further information on your John W. Alexander who was in Dallas County, Missouri in 1850?
