While I have not researched the Ricketson family - I do know that my great-grandfather, Thomas Oliver Riley was married to Samantha Ricketson and she was the mother of my grand-father, David Allen Riley. Obviously the same family, David Allen Riley had a sister named Luch Luraney Riley - I noted the name in your query. The connection with the Wilberns I believe is that another Ricketson sister was married to a Wilbern and Rebecca Ricketson (another sister) was married to David Watson Riley. I do have some pictures of the Riley family.
