Thanks for the all the info you found. You obviously did a lot of research. I too had found quite a bit of it myself.
The one that caught me off guard was that Ella Mae had two children by her first husband. This is incorrect, for there is a mention of Catherine (note spelled with C, not a K) in the 1917 letter Charles wrote his mother. The second daughter, Sadie, the father is definitely not Dillinger. She is my wife's aunt and for the most part, she was raised by Sadie Mae Rioux.
I am hoping that the other questions I have asked will be answered by someone.
