What is a nice middle name for Niamh?

What is a nice middle name for Niamh?
My favourite girls' name is Niamh.

The issue I have is trying to find a middle name that sounds good.

What I would like is -
- A name that is fairly long, to balance the short name Niamh.
- Not a name that is traditionally male or a unisex name. I generally don't find these appealing.

P.S. For those who don't know, Niamh is pronounced like eve with an n in front!

Thankyou in advance! =)
