Hi there.
Here are my favorite to least favorite rankings:
Boys-
Harrison [name_m]Felix[/name_m]-I surprise myself here, since I don’t usually care for [name_m]Felix[/name_m]. But [name_m]Harrison[/name_m] is so strong & heavy (but still handsome), that the quirky lighthearted [name_m]Felix[/name_m] really balances it out. And [name_u]Harry[/name_u] is just friendly & adorable.
Theodore [name_m]John[/name_m]-I do really adore [name_m]Theodore[/name_m]. More than [name_m]Harrison[/name_m], but [name_m]John[/name_m] is just a little bland. And if it’s an honor name, that’s a different story. [name_u]Theo[/name_u] is cute & quirky. Getting really popular if that bothers you.
Christopher [name_u]Elliott[/name_u]-[name_u]Kit[/name_u] is so fun. It’s sporty & posh & friendly. [name_m]Christopher[/name_m] [name_u]Elliott[/name_u] nn [name_u]Kit[/name_u] is one of those combos that barely makes sense, & I love that about it.
Oliver [name_u]Hayes[/name_u]-This is handsome. Really over done, but a charming friendly classic none the less.
Sawyer [name_u]James[/name_u]-I can’t decide if I like [name_u]Sawyer[/name_u]. Sometimes it sounds cool & cowboy-ish, but then sometimes it just sounds too geeky. But I lean towards liking it!
Girls-
Romilly [name_f]Claire[/name_f]-[name_u]Romilly[/name_u] is far & away the most interesting name from your list. I like it. It’s light & sing-songy, but actually really smart & down to earth sounding at the same time. [name_u]Romy[/name_u] is not my favorite, but it’s not bad. And I like [name_f]Claire[/name_f], but it’s not the first thing I’d pair w/Romilly.
Charlotte [name_u]Laine[/name_u]-[name_f]Charlotte[/name_f] [name_u]Laine[/name_u] flows better than [name_f]Charlotte[/name_f] [name_f]Rose[/name_f], even though I personally like [name_f]Rose[/name_f] more in general. And [name_f]Charlotte[/name_f] is a nice classic name. [name_m]Just[/name_m] so so popular. And I really dislike [name_u]Charlie[/name_u] for a girl. [name_u]Love[/name_u] it for a boy! But as a nn for [name_f]Charlotte[/name_f], it seems awkward. [name_f]Charlotte[/name_f] is a soft ‘ch’ & [name_u]Charlie[/name_u] is a hard ‘ch’, you know?
Layla [name_f]Cecily[/name_f]- I don’t mind it. I just find [name_f]Layla[/name_f] a little trendy, but this combo is nice.
Hope this helps.
