Polk is listed on the 1880 census in Edwards Co. living with Norman Webber & family, whose dau. Louetta married Wm. Riley Neal. I don't think the John Burns to Mary Jane Scott is my John Burns. At least I've never heard that name before. All of the children Mary Jane had before John were Potters. John was also married to Melvina Smith in 1875. prior to Mary Jane Dossey.
