[name_f]Annette[/name_f] [name_m]Ray[/name_m] - I love to see [name_f]Annette[/name_f] being used, sheโs so sweet! A little retro but charmingly, and the nicknames are so cute. [name_m]Ray[/name_m] reads as rather masculine to me, Iโm more of a fan of [name_f]Rae[/name_f] for a girl. But if you donโt love the sound anyway, maybe something similar like [name_f]Annette[/name_f] [name_f]May[/name_f], [name_f]Annette[/name_f] [name_f]Rhea[/name_f], [name_f]Annette[/name_f] [name_f]Rue[/name_f], [name_f]Annette[/name_f] [name_f]Rain[/name_f], [name_f]Annette[/name_f] [name_f]Rosie[/name_f]?
[name_f]London[/name_f] [name_f]Beth[/name_f] - I personally canโt get behind [name_f]London[/name_f] as a name, unfortunately 
I know itโs by no means uncommon, but I can only think of the city, and to me this sounds like a [name_f]Beth[/name_f] whoโs from [name_f]London[/name_f]! But I know this is a me issue. Iโd also like the sound of [name_f]London[/name_f] [name_f]Elizabeth[/name_f] more โ [name_f]Beth[/name_f] works fine as a first name, but I find it a little like somethingโs missing when I see it as a middle!
[name_f]Nova[/name_f] [name_f]Florence[/name_f] - [name_f]Nova[/name_f] is not my style, but I like how the sweeter, more timeless [name_f]Florence[/name_f] balances out the more modern feel of [name_f]Nova[/name_f]! It makes for a charming combination.
[name_f]Felicity[/name_f] [name_f]Hope[/name_f] - Really cute! It is a bit wordy, since both names are virtue names, but itโs not too in your face.
[name_f]Milly[/name_f] [name_f]June[/name_f] - So sweet! I love that itโs really adorable, but not too cutesy. I do like the [name_f]Millie[/name_f] spelling more, just because I feel like itโs what most people would default to, but [name_f]Milly[/name_f] is still nice.
[name_f]Marie[/name_f] [name_f]Fleur[/name_f] - Really lovely, [name_f]Marie[/name_f] feels so fresh as a first name, and this combo has spring vibes all over it 
[name_f]Eloise[/name_f] [name_f]Fay[/name_f] - Also lovely! I like [name_f]Eloise[/name_f] a lot, and [name_f]Fay[/name_f] works well with it.
[name_f]Acacia[/name_f] [name_f]Rain[/name_f] - I donโt think [name_f]Acacia[/name_f] would be hard for most [name_f]English[/name_f] speakers to pronounce, although if you live in a more multicultural area, then maybe. Still, itโs an easy correction to make! I donโt love it with [name_f]Rain[/name_f] as a middle name, since both [name_f]Acacia[/name_f] & [name_f]Rain[/name_f] are obvious nature word names it feels a tad bit cheesy to me.
[name_m]Wilson[/name_m] [name_m]Ark[/name_m] - [name_m]Wilson[/name_m] is so cute, one of my favourite -son names! I donโt really feel anything about [name_m]Ark[/name_m] - it could be a cool, edgy word name, but because [name_m]Wilson[/name_m] has this charming old-mannish feel to it, the very daring and modern [name_m]Ark[/name_m] kind of clashes with it to me.
[name_m]Atlas[/name_m] [name_m]Royal[/name_m] - [name_m]Atlas[/name_m] is a handsome choice 
Iโm not fond of [name_m]Royal[/name_m], it feels a little tacky to me, personally, and kind of romanticizing the idea of nobility in an uncomfortable way? Iโm likely reading too much into it, but thatโs just how I feel I also think itโs a bit too wordy here, since [name_m]Atlas[/name_m] is also a word. Maybe something like [name_m]Atlas[/name_m] [name_m]Ronan[/name_m], [name_m]Atlas[/name_m] [name_m]Rohan[/name_m], [name_m]Atlas[/name_m] [name_m]Reuben[/name_m] etc?
[name_m]Lewis[/name_m] [name_m]Tyler[/name_m] - [name_m]Lewis[/name_m] is really underused, I think he sounds really friendly and cozy! I think it does work with [name_m]Tyler[/name_m], since theyโre both fairly established names by now, but I do like [name_m]Lewis[/name_m] [name_m]Theo[/name_m] a bit more.
[name_m]Harris[/name_m] [name_m]Rowan[/name_m] - Really cool combo!! It feels on-trend and current but not overwhelmingly modern, and I really like the light, handsome sound of [name_m]Harris[/name_m].
[name_m]Rene[/name_m] [name_m]James[/name_m] - Itโs fine, but Iโm not crazy about [name_m]Rene[/name_m]. I think itโd be mispronounced often, and it feels a bit feminine & dated to me because of its similarity to [name_f]Renee[/name_f]. But the classic and handsome [name_m]James[/name_m] works well with it!
Ellium [name_m]Stone[/name_m] - I donโt really get the appeal of [name_m]Stone[/name_m], unfortunately! I like word names, and nature word names especially, but a stone isnโt an especially attractive thing to name a child after, at least to me It also does feel a lot more out there than your other combos, if you care about cohesion, since Ellium is rare, and [name_m]Stone[/name_m] is also very brave. That said, I really like the idea of Ellium! It sounds very on-trend and has a lot of familiar sounds, like a combination of [name_m]Elliott[/name_m] and [name_m]Callum[/name_m], so itโd be entirely unique but not shockingly out-there. Iโm not personally a fan of made-up names, but it has an objectively attractive sound!
[name_m]Henry[/name_m] [name_m]Kai[/name_m] - Itโs a cool choice! Like some others on your list, it feels very on-trend. I donโt think it matters that [name_m]Henry[/name_m] is more of a classic while [name_m]Kai[/name_m] has only become popular in recent years. Theyโre both very popular, trendy names in 2024, so they work well together imo!
[name_m]Arthur[/name_m] [name_m]Edmund[/name_m] - I love the timeless vibe of this combo, really handsome! And I just adore [name_m]Edmund[/name_m]

Cool combo though.
wilson is very soft and ark adds some edge to it.
