My best friend's name is Erika, and I've always loved it! I think it's nice, and easy to use for an adult, but also super cute for a little girl. Her brothers sometimes call her Rika (ree-ka) and Errie (Eh-ree). It's definitely my favorite girl's name that starts with an E, and I think it looks really nice spelled with a K.

For a boy, hmm... I think Elliot is my favorite out of what's been suggested so far, and I can't really think of anything else... or Edward!

I like the name Emerald for a girl. Again, this could be an Emma option name. But I would use the full name personally.
She will shine in a sea of Emmas.
