Alexander Dugger and wife Catherine Bailey had numerous children per the 1830 and 1840 census. As far as I know, none of these are completely proven. I have placed a few here based on circumstantial evidence, and some of them were listed by Frances Dugger Rowan in her Dugger book, or so I'm told. Also data shared by Robert G. Duggar and Robert E. Duggar have helped to sort this family out a little bit.
