I work with the Madison County Genealogical & Historical Society and will be glad to try and help you.
Did Robert, Emily and Alice May Litterell live in Madison County? Can you send me some more information about them, such as estimated dates of births and deaths on them. I will see what I can find but I will need more to go on in order to know where to look. Is Alice May the daughter of Robert & Emily? Who did Alice May marry?
