Hello, Dot, I am descended from Isaac ROOKS of Screven County, GA, and believe the 90 year old living with Mr. Taylor to be my ancestor. I also believe he was married to Abigail KEMP MERCER, daughter of Solomon KEMP and his wife, Margaret. Do not know if they had any children, but possibly at least a son, Isaac ROOKS, because in 1843 in Screven County, GA, an Isaac ROOKS marries Sarah FISHER, and they had three children, Susan, Mildred and Isaac DeKalb ROOKS. In one census, however, we find the older Isaac living with Sarah, Susan, Mildred and Isaac DeKalb ROOKS and no younger Isaac in the household who might be the father of the children. I am descended from Isaac DeKalb ROOKS. Wish I could be of more help. Agnes Donnelly
