Cynthia, glad to find another Waggoner researcher in my line. I haven't verified Drady's parents but one place you might start looking is
http://www.rootsweb.com/~deschart/z0000500.html

The Juana is an error because one of the IN deeds is written from Jacob Waggoner Jun and Drady, the 'Jun and' became corrupted into Juana. Her first name is Drady/Drada, and I have HEARD that it is because her mother was a Darby, but that is speculation, and as you see, the website chart gives another mother. However, that site also gives Jacob as the s/o Henry and Ketrina which unfortunately isn't true.

I have Jacob and Drady's marriage record from Pulaski Co KY and an assortment of other records including her death in IL, and some from Indian Creek IN. Let me know if you would like more detail.
