My grandfather Bennie Stuart Ferguson was the son of Milton and Minerva Miller Ferguson from the Morgan County area, although my grandfather later lived in Cass, Menard & Sangamon County. He died in 1963. Milton Ferguson's father came here from Ireland. Minerva Miller's mother was a Cleveland, and there is a DAR line there. Dont know if these are related to the Fergusons you are interested in. D. Ross
