Seeking any information on Sarah Bates, wife of Milton Marion Duke. She would have been born about 1840-50, was in Chicago at the time of the Chicago fire (1871), then moved to Bloomington, IL, where she is believed to have died. A son, Louis Milton Duke, was born in 1873, just a short time after her husband was killed an a RR derailment. Any help would be most welcome. Thanks. Bob King
