Those are simply happy coincidences after the fact. I bet if Lucas had used one of the other randomly generated names for the character, we'd likely be sitting here repeating alternate lore about its significance and foretelling of future events in the saga.
It's just that "mythical quality" given to the franchise (for better or for worse) and massive popularity that fuels such things.
You're right...it seems so...strange to see some epic pop-culture being named after an actual person without further meaning.
It's not unheard of though...Harry Potter was named after a colleague of the writer. Very un-epic
