[name_m]Hi[/name_m] all!
I’m writing a story about a set of triplets who find out their dad is a [name_f]CIA[/name_f] agent and try to find their missing mother. I already have two names, but the third sibling is proving difficult! I originally wanted to call her [name_f]Charlotte[/name_f] (nn [name_f]Shari[/name_f]) but I don’t really think it fits in with her siblings… (Their dad’s name is [name_m]Alexander[/name_m] btw)
[name_f]Jamaica[/name_f] [name_f]Rose[/name_f] [name_m]Wright[/name_m] (nn [name_u]Jamie[/name_u]): the oldest daughter of [name_m]Alexander[/name_m]'s, she was born with the mixed genes of her parents. With her round face and a nose like her dad, and her eyes, height and hair colour from her mother, she is a quiet leader and got the brains in the trio. She detests how [name_m]Luke[/name_m] teases [name_f]Shari[/name_f] and is always seen to be the motherly influence on her siblings. Though she is oldest, she lets [name_m]Luke[/name_m] be the enforcer of the family. She is the first to figure out who their mother is.
[name_m]Lucien[/name_m] [name_m]Hamilton[/name_m] [name_m]Wright[/name_m] (nn [name_m]Luke[/name_m]): He is a carbon copy of his dad, however, he inherited his mother’s apparent shortness (there was a 15cm difference between the pair according to [name_u]Alex[/name_u]). He likes his video games, his sport and his friends, but he knows that family is the most important of all. When he was younger, he was the one who initiated getting a present for their dad on mother’s day too, because he was both to all of them. [name_m]Luke[/name_m] has a nasty habit of being quite rude to [name_f]Shari[/name_f], his younger sister. He is the brawny sibling.
Third Sibling (Originally [name_f]Charlotte[/name_f] [name_f]Bronte[/name_f] [name_m]Wright[/name_m] nn [name_f]Shari[/name_f]): The youngest triplet of [name_m]Alexander[/name_m]'s. She was the only one to inherit her father’s tallness (standing at roughly 177cm), leading people to believe she is the oldest. The other difference to her other siblings is that she looks a lot like her absent mother, with blonde hair and green eyes. She is quite smart, but excels at sport also. [name_f]Shari[/name_f] and [name_u]Alex[/name_u] talk in private about life as they share the same views on almost everything, unlike her older siblings. She is the first to figure out that her father is more than just a science teacher.
Any and all suggestions will be looked at 
Thanks x
their dad is very tall, brown hair, brown eyes, while their mother is petite with blonde hair and green eyes.
