Or you could argue that it is a lesson from the journey of sin (Tower of Babel) where they tried to be as reat as God, or create a Dominion apart from God. So they may see it as equate oneself with god.
Mary probably changed since she is NOT God, and in the Catholic tradtion, should only be venerated, like a Saint, and since saint's names are used, I guess it followed the same pattern.
However, I did realize your statement on
Mary only appearing later. While looking at some
Royal genealogies, I did not see
Maria,
Mary,
Marie or any other forms of the name until the 15th century.
