[Opinions] Re: Ruth and Naomi
I'd say Ruth and Naomi would be too much.
I could see either grouped with Miriam and Judith as sisters, but not together. Personally, I prefer Ruth with those two, and also overall.
I like that you're using the Hebrew pronounciation. I agree, it sounds much better.
About Nina, I remember seeing Christine in a few of your combos before. If you end up using that, what about Christine NN Nina? It's not too far of a stretch.
And one last note, a funny coincidence about your question: My best friend's mom is a Naomi, and her sister is a Ruth. It's kinda funny that I actually know a sibset like that in real life.
