Unlike Merrite, Barger was described as being the picture of health as a child, which
falls in line with Watson's description.
Finally, it was discovered that Barger's middle name was,
in fact, Albert and that is what he always went by even into adulthood, which would explain how Watson came up with the name“Albert B”.
Barger's medical records also indicate that he was
a healthy weight for a baby, whilst Merrite was underweight, the latter of which doesn't at all fit with the known images(and video) of Albert showing a plump, robust infant.
