Character names - help i'm stuck

I am writing a teen romance sort of story and the main character’s name is Lilith/Lily. I have siblings that i need to name, the oldest is a boy and he is 15 and he is the love interest. Right now his name is Ezra but i don’t like it anymore. His 7 year old sister’s name is Beth right now and i really can’t remember why i chose that name. I currently like the names Willa, Aurora, Clover, Faye, Simone and Gwyneth/Gwen. Does anyone have any suggestions for her brother and what i should name her, i am open to any suggestions, Please help!!

Also happy for any other ideas instead of lilith!

I might stay away from making both teens have nature inspired names, even in their families. It just might get a little confusing if they are similar styles. I like [name_f]Lilith[/name_f], it’s a variation of [name_f]Lily[/name_f] that doesn’t get used as often.

[name_m]Lucian[/name_m] & [name_f]Gwyneth[/name_f]
[name_u]Jonah[/name_u] & [name_f]Gwyneth[/name_f]
[name_u]Sterling[/name_u] & [name_u]Antonia[/name_u]
