Oh, but the answer may yet be out there. Dr. Charles Tracy SOUTHWORTH left a huge paper trail. He had a biography in the History of Monroe County Michigan. He was the son of a doctor, went to the University of Michigan, College of Physicians & Surgeons in New York City, Medical School in Paris, France, medical residence in Havana, Cuba, interned University of Madrid Medical Hospital, was surgeon general for Santa Anna in Mexico, returned to Monroe, Michigan and married Frances H. BLAKSLEE, was a surgeon in the 18th Michigan Vol Infantry (Civil War) and lived and worked in Monroe for 20 years until he was struck by a runaway team and died of injury of the heart. So there may be records of visits to Ogemaw, or relatives here. Maybe there is a BLAKSLEE connection. When the father died, the girls were with their stepmother and her three children. Their stepbrother, Charles Tracy Jr, was just off to Detroit College of Medicine. So right after their father's death, both daughters of Frances BLAKSLEE SOUTHWORTH end up in Ogemaw, but none of the other children. Still a mystery. Thanks for the information.
