Kezziah Terry and Margaret Brunson

So I may have discovered the confusion about John Daniel Sr.'s mother and her name. His father, Daniel Holladay Jr, was married to Margaret Brunson sometime before 1773, and then to Kezziah Terry sometime before 1792. It was probably a plural marriage situation. Kezziah is John Daniel Sr.'s mother... although there is some confusion over his brother Daniel William Holladay. I can't determine which woman was his mother! Any brilliant discoveries/insights much appreciated!
