[name_f]Coral[/name_f] → unexpected with a sharp, strong sound, but with a pretty feel - it puts in mind a pleasing colour and connection to the sea.
Not sure if it’s a thing where you are, but [name_f]Coral[/name_f] is the name of a chain of betting shops where I am, which could be a con.
I do slightly prefer the similar [name_f]Coralie[/name_f] but I love the fact [name_f]Coral[/name_f] is on your list.
[name_f]Kassia[/name_f] → sparkly, sassy, and cool, with a sweet meaning and a fresh-but-established. Cons could be that it’s got two well-known spellings (Cassia / Kassia) and two pronunciations (Kass-ee-uh and Kasha) - in regards to pronunciation, I love Kass-ee-uh but Kasha feels a try hard? Not even sure why. Still, I like [name_f]Kassia[/name_f]!
[name_f]Keely[/name_f] / [name_f]Keeley[/name_f] → rugged and playful in sound, it’s got this sweet but breezy feel. It reminds me of [name_f]Keeley[/name_f] [name_m]Hawes[/name_m] so it’s got a bit of glamour to me. Cons could be the multiple spellings and similarity to popular choices like [name_f]Kinsley[/name_f], [name_f]Kallie[/name_f], and [name_f]Kelly[/name_f]?
[name_m]Adair[/name_m] → daring, bright, outdoorsy and cool, with a hint of gentleness too. I personally like the fact is sounds like dare, but I can also imagine if this is for a real life kid, ‘do you want a dare?’ comments might happen?
[name_f]Shea[/name_f] → gentle in sound, but with a confident, breezy vibe. It’s got cool meanings too! I guess people might mispronounce it - like shea butter? or shee-uh?
[name_m]Tripp[/name_m] → snappy, sporty, and cool, with a sort of ‘travel’ vibe or a nod to travel. For a real life child, I guess ‘tripping up’ jokes could be made, or some might assume he’s a 3rd owner of the name (like [name_m]James[/name_m] [name_m]Henry[/name_m] III ‘Tripp’) but then, I’ve met a [name_m]Trey[/name_m] who was just a [name_m]Trey[/name_m] so
[name_m]Ty[/name_m] → love a short name and I like the kind of relaxed, sunny, surfer vibes this gives. A con could be that people assume it’s a nickname for [name_m]Tyler[/name_m], [name_m]Tyson[/name_m] or Tryone
[name_m]Zander[/name_m] → a solid option with a bit of edginess to it, but I just find it a bit meh, like [name_m]Alexander[/name_m] trying to be more interesting but still being [name_m]Alexander[/name_m]
[name_m]Zane[/name_m] → international, versatile, and quite nice. I don’t love it (maybe because of a bad association) but that’s personal and I think it could totally work on your list. One disadvantage is maybe the multiple spellings - [name_m]Zayn[/name_m], [name_m]Zain[/name_m], [name_m]Zeyn[/name_m] and [name_m]Zayne[/name_m]
