I have since learned that "Archada Johnson" is in fact Archada Johnson Smith.Yes, Johnson was her middle name. She was the daughter of Lemeul (also known as Samuel) Smith and Susanna Milam.Maybe Samuel's mother was a Johnson, though I do not have any information on him.Would like to find info on him if possible. Susanna's nickname was "Sukey".After Samuel died Susanna married Wm. Dowdy.
Thus Mary Johnson Parchman Thomas' middle name is the same as her grandmother's.
Susanna Milam was the daughter of James Milam, Sr. son of Adam Milam.Susanna Milam was the sister of Adam Samson Milam who married Dicey Sikes.
