Djalma Davenport's sister Sara Icyphenie (Davenport) Green was my great grandmother, therefore Djalma is my Great uncle.
I am not sure of the origin of the name Djalma, but have heard the davenports might be of German descent.
Are you tracing Belle(Howard)Davenports line and how are you related. I believe the Howards lived in the Kenney/Clinton Illinois area. Is there any specific information you are looking for?
