citizenprecious, what good taste you have!
From your list Puffling, a few of those are lovely with a little 'tweaking'. Joyce is vile but Joy is lovely and is my dd's middle name. I love it.
beryl is a bit of a statement name, but it's a nice sound as is Meryl. They will come back. They are 'next up' I think. Edith, Agnes, Ivy, Iris, Meryl, Beryl....
Janice makes me think of that woman chandler nearly married on friends! Janis is slightly cooler for some reason. But it's not great.
Maureen is awful, but Muireann is cool. Mwirren.
