I read somewhere that
Mora is the Spanish for blueberry once. (I don't speak Spanish, so that could be entirely wrong.) The point is that the meaning "blueberry" alone was enough to draw me to the name. What a cute meaning.
Now, whether or not I have the guts to like the name using the English word is another story. I know Blue is being used for girls now.
On balance, it's just too "out-there" for me to use in English. Perhaps tucked away in the mn spot it couldn't do much harm, other than make me hungry for pancakes.
