Linda, John R. Duty was my second great grandfather. One of his sons was James G.A. (Jim) Duty who was married to Littia Anna WHITLOCK Duty. (your George Washington Whitlock, JR. was her brother and your Caroline DUTY Simmons-Davis was Jim Duty's sister.) James G.A. (Jim) and Littia Anna's son, Ernest Samuel Duty was my grandfather. My mother was the oldest of the ten children raised by Ernest Samuel Duty and Hattie SIMMONS Duty. (They lost four children as infants and one at age 14.) So, there certainly are a lot of us. Please let me know if I need to be more specific. I would be only too happy to share what I know. But, I, too, am lost on John R. Duty. Please feel free to email me if you wish. However, except for my more immediate family, you seem to be fairly close to what I have on the older of our ancestors--now, if we could just find John R. Duty!
