June-Please refer to message 180 and 190 to answer some of your questions. There was at least one other kid of John B. Harley.His name was Irving S. Harley.He was raised by his grandmother- Mary Bullock.She died in 1882.Emmoline died when he (I.S) was 3 years old.
John B. left home after his wifes death and resided in Alabama. Reason for leaving is unclear. It is said that John B. died in 1857 but I have not verified this.
Some info on this family may be found in "Men of Mark in SC"J.C. Hemphill editor , Vol 3 1908
Hope this helps.I have verified very little of this info so take it at your risk, but it gives you a place to start.
