My branch of the Morrows/Kiddoos were not the Aledo branch but I do have William KIDDOO and Catherine Delila VANCE in my database. I only have two children for them.
William KIDDOO and Catherine Delila VANCE
m. 3 March 1853
Evila Jane Kiddoo b. 8 Dec 1853 m. Willard Easley

I do not have Rachel Kiddoo or Ralph Davison.
I am a GRAVES from my father's maternal side. They were Jamestown VA, to KY and TX .
Never heard of any in IL but checked out all of the Ralphs and the others in your note - nothing there.
Let me know what you have and what you need on the Kiddoo couple - Nancy
