I am also descended from James Madison Barker. However, I do not have him with a son named Cicero - or did I misunderstand your message. I have his children from his first marriage to Mary Anna McDaniel as William Madison, Sarah Frances, Zeriah Margaret and Nathaniel Henry. From his second marriage to Mary Ann Daniel I have Louisa Jane, James Monroe "Chris", Mary Susan, Elizabeth Ann, Patrick Henry, John Floyd, Alfred Scott, George Herbert, Thomas Arthur and Benjamin Rush.
I am interested in where you found a Cicero in his family.
