Many Johnson and Johnston descendants (of the Johnson and Johnstons of early Virginia) rely on and perpetuate the claims made in the 1979 work of Hugh B. Johnston and Eddis Johnson.
However, subsequent research by Mark Valsame in the 1990s and early 2000s argues against these claims. Read more here:

Specific to this Robert Johnson, Valsame points out that the 1979 work conflated two different Robert Johnsons:
"The authors merged together two different Robert Johnsons. One Robert Johnson was living as late as the 1690s and had a wife Katherine. Robert and Katherine had a daughter Mary Johnson, who was the wife of James Johnson. This is proven by a deed. This couple, James and Mary (Johnson) Johnson, are allegedly the earliest verified direct ancestors of Lyndon Johnson. The other Robert Johnson died leaving a will in 1733 (devised in 1732). He is clearly a much later individual. Again, these were two seperate men, but Hugh B. Johnston and Eddis Johnston merged them together as one man who lived from ca. 1643 to 1733, who had two sons named John by different marriages. That is nonsense."
Therefore, we need to separate out the two men into two different profiles and detach/re-attach the children appropriately:
- Robert Johnson living as late as the 1690s with wife Katherine _____ (Valsame also points out that there is NO proof that she was the daughter of Arthur Allen and Alice Tucker). Their daughter Mary Johnson married James Johnson. They also had a son John Johnson (that the 1979 genealogy called "the elder")
- Robert Johnson who d in 1733 (will dated 1732). His wife was Ann. They had a son named John Johnson (that the 1979 genealogy called "the younger").
