@George,
Funny Latin George. We would have fun calling my late husband Bud, Bud Ox.
Who in the world would sing Rock a By Baby in the Tree top to a child. Perhaps the meaning had to do with this:
Another legend finds the rhyme's origins steeped in the political climate prior to the Glorious Revolution of 1688. The baby refers to the heir born to England's King James II. Supposedly written in an English pub, the original lyrics served as a death wish upon the newborn prince in hopes the empire would be overthrown.
How about B.J. Thomas now:
