Can anyone tell me when Preacher Doherty and his wife, Rosa Lee Johnson died and what they died from. They allegedly died on the same day. They are buried in unmarked graves in the Calaway Cemetery. They were last found on the 1920 census for Ouachita Co, Union Twp (Bearden). It is thought they died around Thornton. Her parents were Andrew Johnson and Elizabeth Barnhart. His parents were William Doherty and Tennessee Quarles.
