I have some info on this line. I've been searching for Duncan's older brother - William H. I believe he was the father of my g.grandmother. My g.grandmother was living in the household of Duncan & William's younger sister - Janie. Janie married Wm. R. Mallon and in the 1880 census of Pierce Co. they were living in Blackshear, Ga. I'll be happy to share anything I have with you. Thanks, Judy Jumeaujs1@aol.com
