Girls:
[name]Claire[/name] – Sweet, pretty, goes with [name]Alyssa[/name].
[name]Cara[/name] – Sweet, pretty, goes with [name]Alyssa[/name].
[I like [name]Cara[/name] better than [name]Claire[/name], but I like [name]Claire[/name] with [name]Alyssa[/name] better than [name]Cara[/name].]
[name]Brynn[/name] – Sweet and cute! Definite sister match
[name]Ella[/name] – Sweet, popular, but I don’t like it with [name]Alyssa[/name]. They have too much of the same sound I think. [name]Alyssa[/name] and [name]Ella[/name]… Nope.
[name]Camille[/name] – Pretty, though not the type of name I usually like. I like [name]Camilla[/name] better. [name]Alyssa[/name] and [name]Camille[/name] have different feels to me.
[name]Avery[/name] – It’s okay. Doesn’t seem to fit the style of your other names, and I really don’t like [name]Alyssa[/name] and [name]Avery[/name] together.
[name]Mya[/name] – I love [name]Mya[/name] (prefer [name]Maya[/name] or even [name]Maia[/name], but that’s me). [name]Alyssa[/name] and [name]Mya[/name] aren’t perfect together, but it’s an awesome name.
[name]Kate[/name] – I can see these as sisters, but personally I’m so over [name]Kate[/name].
[name]Eden[/name] – I don’t really care for this name personally, but that’s just me. It’s a pretty and, depending on your area, could be a distinctive name. I think [name]Alyssa[/name] and [name]Eden[/name] sound like sisters!
[name]Maren[/name] – I’ve always found this very pretty, and it’s quite unusual where I am from.
[name]Lauren[/name] – Pretty, soft, sweet, same style as [name]Alyssa[/name], and a definite sister name!
[name]Chloe[/name] – I feel like [name]Alyssa[/name] and [name]Chloe[/name] are the same type (type? style? not sure what the right word is, but they match), but where I picture an [name]Alyssa[/name] more soft and sweet, I picture a [name]Chloe[/name] more bold and out-going. And I mean all those words in a positive way. I like them together a lot.
[name]Kathryn[/name] – [name]Don[/name]'t like the spelling, and not sure I like it with [name]Alyssa[/name] at all.
[name]Celeste[/name] – I’ve just never liked this name. It seems like it’s trying too hard.
[name]Alaina[/name] or [name]Alayna[/name] or [name]Alana[/name] – This is a name that I want to like, because I know several and they are all nice girls (or babies who will hopefully be nice girls). I just can’t like it. I don’t know why, but I always get a “made-up name” vibe from it, which is ridiculous. Plus [name]Alyssa[/name] and [name]Alaina[/name] is way too matchy-matchy.
[name]Brenna[/name] – This is cute. Not sure how I feel about [name]Alyssa[/name] and [name]Brenna[/name] together though.
So my in conclusion for girls is that I would narrow it down to [name]Claire[/name], [name]Brynn[/name], [name]Eden[/name], [name]Lauren[/name], and [name]Chloe[/name]. (I decided to just pick 5, which was hard!)
Boys:
[name]Landon[/name] or [name]Landen[/name] – I really hate this name. I don’t like the way it feels in my mouth when I say it (I know that sounds stupid, but there it is). I can’t even be objective about whether it sounds good with [name]Alyssa[/name], because I just strongly dislike it.
[name]Ryan[/name] – [name]Alyssa[/name] and [name]Ryan[/name] really sound like a brother and sister to me. The only thing is that [name]Ryan[/name] doesn’t feel fresh to me anymore, but it is a cute and handsome name.
[name]Brendan[/name] – I like [name]Brendan[/name]. It’s definitely my favorite of the [name]Bren[/name]-/[name]Bran[/name]-/[name]Brad[/name]- names. [name]Alyssa[/name] and [name]Brendan[/name] go together very well.
[name]Tristan[/name] or [name]Tristen[/name] – I know an [name]Alyssa[/name] and [name]Tristan[/name]! I don’t care for the name personally, but it’s a nice name (just not me). They match very well.
[name]Kai[/name] – I’ve never liked this. I always feel like you are trying to be cute with it.
[name]Cade[/name] – I adore [name]Cade[/name]! I read it in a book once, just a minor character in GWTW, and have thought it strong and handsome ever since. Definitely my favorite from you list!
[name]Caden[/name] – Oddly I find this a little feminine (the first one I ever knew was a girl). It does go well with [name]Alyssa[/name] and you can still call him [name]Cade[/name]!
[name]Anderson[/name] – I like this name on principle, but not on a real person. Plus I think [name]Alyssa[/name] and [name]Anderson[/name] sound weird together.
Narrowing the boys, it’s [name]Cade[/name] for sure! With [name]Brendan[/name] or [name]Tristan[/name] (and maybe [name]Ryan[/name]) as alternates.
