Hello! So, I’m writing a story centered on a group of teens around 13-15 years old. I have a few names for them already, but I’d like some more options. I need suggestions for first and last names that come to mind, please. 
Alright, so here’s the first twelve characters, as I’m still developing descriptions for the others:
Character One: She has thick, wavy honey blonde hair that falls down to her elbows. Her skin is lightly tanned with a few freckles on the bridge of her nose, and her round eyes are a vibrant shade of jade green. She is short and slim, and often dresses in athletic clothing, favoring pink and grey. She is extremely intelligent and outgoing, both a popular and straight-A student.
First Names Considered: Macy, Addison, Kara, Isabella “Bella”, Beatrice
Surnames Considered: Baker
Character Two: She has thick medium brown hair that falls down to her waist in tousled curls. Her skin is pale and sprinkled with freckles, and her murky grey-green eyes are shielded by a pair of rectangular glasses. She is tall and chubby, and often dresses in jeans and t-shirts, preferring to not draw attention to herself by covering her arms with a jacket and often wearing black and navy blue. She is a withdrawn and socially awkward wallflower, a bit of a slacker who seems to be constantly on edge.
First Names Considered: Willow, Pandora, Maeve, Farrah, Beatrice
Surnames Considered: Butler, Delaney
Character Three: She has long, wavy light brown hair in a braid that falls down to her waist. Her skin is lightly tanned, with rosy, freckled cheeks. Her almond-shaped eyes are a pretty shade of hazel, and she has a beautiful smile though doesn’t seem to know it. She is medium height and slender, and often wears tank tops and sundresses. She is withdrawn and shy though incredibly sweet, and a bit more outgoing than Character Two.
