I like it very much.
Olive makes me think of olives, which I like very much as a menu item but not as a name. In my family tree somewhere there is a distant cousin who was born in the very early 20th century and named
Olivia; she apparently insisted on being known as
Olive, and I really think it's a bad choice.
Olivia has grace and elegance and a dancing rhythm, all of which
Olive lacks.
