Unique Baby girl names / middle names?

Hello! I am a 15 year old, and I am creating a personal persona. However, I need a middle name for my persona, Lily! I do not want a made-up name, boring, overused, soft flow with Lily, and please no letter 'C' or 'D' in it, and I also need a last name for this.

What I love, but can not use (or just the names i don't want to use for personal reasons): Lily Kay, Lily Valencia, Lily Jade, Lily Rose, and Lily Emmie My tastes of names are: Emmie, Ella, Eleia, Lily, Kali, Valencia, Kay, Aaliyah, and Elora. Are there any other E girl names? I looked at all these names, and I hated them. And it's not like I'm naming a real baby, but somehow, even a name just for myself, I still don't like them.

Also, is it okay or acceptable to share a name with a cousin? Example: Cousin name: Chloe. Your name: Chloé. Honest thoughts?
