I think it is worth realizing that it
is only in fable where the prime characters names have significant meanings.
Can you imagine the monarchy in Britain calling their newborn infants Rex or
Prince? It is only where there is no legitimacy as in stories where the names
of characters require linguistic or semantic clues for reinforcement.
Jehovah is drawn from the Latinized version of YHVH in the English language. In the earliest KJV, the name of this god is rendered Iehovah demonstrating the comparatively recent development of the letter J (in English) arising from a capitalized initial letter 'I'.
If we trace the history of Jehovah as a divinity, the fact that he began as a Canaanite god, the son of El and brother of Chemosh and sixty eight other brothers...somewhat diminishes the 'almighty-ness' which was later attributed to him. Yahweh is depicted as a cow-horned idol sitting with his female consort Ashera in early stone reliefs from Canaan (but don't tell the JW org!)
The concept of gods or God constantly evolves since religion is not based on fact but mental constructs i.e. the human imagination. Ideas of greatness and power are borrowed from earlier literature to give weight to the holiness of a religious teaching.
The JW org has done this very thing by appropriating the name Jehovah and loading it with doomsday connections and power as their own identifying mark.
