right. I know it was his initials, that doesn’t answer why the use of the name Jeb instead of John. Perhaps, he feels John is too common for him.
Oh, and my comment on why use Jeb instead of John - it was his momma that came up with it, you have to believe it was, rather than Jeb himself deciding John was too common. My understanding is he was called what momma called him, from the beginning, not a decision he made later.
If anyone knows differently, feel free to weigh in.
