The only McDade I could find in the Johnson Co AR area in 1900 census is a widow Martha McDade in Franklin Co AR. She is 33 and her 64 y/o mother Sarah Goodnight is living with her and several children. ??? In 1920 census Dan Treadwell and Matty are still in Johnson Co. Batson twp,Dan is 75 Matty is 53 and Gladis and Harl (prob Daniel H) are in the home.
