We have a Ds called Jesse, and a Dd called Ellie (she's older - it took off the year she was born... now she's starting to have issues with having a popular name).
We're expecting another little girl, and we really want to avoid popular names no matter how much we like them as we're keen to avoid the issues we're having with DD1.
At the same time I don't want anything too out there - although I like unusual names, we'd like something that fits with us as a family, and with the other Dc's names.
So what's the happy medium? 
Others we've considered are...
Lois
Hattie
Lila
Some more I can't remember!
