I once knew twins called
Minerva and Monopoly, which was a bit much, so I've never really considered
Minerva on its own, but now that I do I actually find it very pretty. I guess they'd end up called
Minnie at school though, and that was the name of my cat when I was younger, so that puts me off a bit.
I'd say for mns you want something simple and less frilly -
Minerva Kay, etc
