It’s such a hard question!! I love [name_f]Clara[/name_f] & [name_f]Bess[/name_f] too, but there’s just something so lovely about [name_f]Anna[/name_f] 
I love how international and timeless she is, I love the adorable nickname [name_f]Annie[/name_f], and I love her imagery: she’s always felt like flower fields and windmills to me!
For the boys, it’s somehow even harder for me 
I love almost all of these names! [name_m]William[/name_m] would be the closest second, but I just have such a soft spot for [name_m]Francis[/name_m]! He’s honestly so underused nowadays, and I love its softer, gentler sound, as well as the nicknames, from the darling [name_f]Francie[/name_f] to the much livelier [name_f]Frankie[/name_f].
[name_f]Katharine[/name_f] “kit” + [name_m]Francis[/name_m] 
I love your list! 
I’m going to choose [name_f]Katharine[/name_f] 'Kit’ (Kitty-Fleur! Obsessed still) and [name_m]Laurence[/name_m]. [name_m]Laurence[/name_m] is so handsome! And there’s something so crisp and sleek about [name_f]Katharine[/name_f]. For some reason I also think both of these names feel a bit gothic and vampiric in the most amaaaazing way
[name_f]Constance[/name_f] or [name_f]Rose[/name_f] for girls and [name_m]William[/name_m] for boys!
[name_f]My[/name_f] favorite of your girls is [name_f]Katharine[/name_f] ‘Kit’ !! I love the regal and beautiful spelling of her, she’s very classy and defined, and then I also adore the spunky and playful [name_m]Kit[/name_m] as a nn for her!! She just feels so perfectly balanced and so you!!
From my boys list, my favorite is [name_m]Nathaniel[/name_m]. He just feels very rugged and outdoorsy, while still being a down-to-earth, soft classic!! He has great nickname potential, and pairs fabulously with all of your other names
for girls, my favorite is definitely thea! simple, yet spunky and strong
for boys, I have to go with milo. I wouldn’t use it personally but I know a sweet boy with the name who brings it close to my heart
Oh, lovely names! All very classic. [name_f]My[/name_f] favorites are [name_f]Clara[/name_f] and [name_m]James[/name_m]! But they all are great
[name_f]Rose[/name_f]. This name is very timeless and I believe it will always be in style, it’s one of the prettiest girls names I can think of!
[name_m]James[/name_m]. I love the masculine strength of this name and it also has the added benefit of being traditional.
love your list! for girls, it’s really hard to choose between clara and thea, but i would have to say clara today because it’s just so pretty. in terms of boys, it’s gotta be milo, because milo is one of my all time favorite names and it’s been on my list for a really long time!
thea & james
[name_f]Rose[/name_f] 
[name_m]Just[/name_m] a stunning, classic name. I’m always shocked by her simplistic beauty. It’s a longtime favorite for me, and I just couldn’t resist!
[name_m]William[/name_m] 
I love how princely [name_m]William[/name_m] sounds. So much rich history behind this solid classic… And then there’s Will–charming, classic, sweet [name_m]Will[/name_m]. He is just so cozy and comforting.
You have such a gorgeous list! I couldn’t resist shouting out [name_f]Clara[/name_f], [name_f]Thea[/name_f], [name_f]Constance[/name_f], [name_m]Milo[/name_m], and [name_m]Benjamin[/name_m]!
[name_f]Anna[/name_f] – poised and international with buoyant energy
[name_m]Laurence[/name_m] – warm, distinguished, and underused classic with great nicknames
Girls:
Lots of good choices here but I like [name_f]Clara[/name_f] best - it’s beautiful and classic but just unusual enough I’ve never actually met one. It’s just such a sweet name. 
Boys:
I can’t use it, but I like [name_m]Milo[/name_m] the best. I just love all the short “o” names, for both genders - [name_m]Leo[/name_m], [name_f]Cleo[/name_f], [name_f]Juno[/name_f], [name_m]Milo[/name_m], Elio… It’s cute and spunky.
[name_f]Rose[/name_f] - she’s one syllable of beautiful, understated perfection with unusual sounds (in a girl’s name) to boot. [name_f]Rose[/name_f] is somehow elegant and sassy.
[name_m]Oscar[/name_m] - geeky chic, cuddly but dignified.
I’m going with…
[name_f]Constance[/name_f] → strong, elegant and powerful, but pretty and approachable too. I love the nickname options of [name_f]Tansy[/name_f], [name_f]Coco[/name_f], [name_f]Connie[/name_f], Caz and [name_m]Taz[/name_m], but also just as a full name too
[name_m]Nathaniel[/name_m] → elegant and gentle but strong too, with charm and versatility. I like how it’s a name people know but it’s not overly popular. Also have a soft spot for nickname [name_m]Thaniel[/name_m] (controversial maybe 
) but great as a full name too
i love all your names so much!
i love [name_f]Clara[/name_f] and [name_f]Thea[/name_f] most out of the girl names. i couldn’t pick between the two.
for boys, my favorites are [name_m]James[/name_m] and [name_m]Milo[/name_m]. again, i couldn’t pick between the two.
[name_f]Clara[/name_f] & [name_m]Laurence[/name_m]
[name_f]Thea[/name_f] - a long-time favourite of mine. I tend to prefer longer names for girls, but there’s just something about Thea’s simplicity that I enjoy.
[name_m]Oscar[/name_m] - I know a few boys named [name_m]Oscar[/name_m] and they’re all lovely, so that warms their name up to me. I like how it’s timeless and not trendy, but just goes along with the flow and feels like a warm, friendly name.
[name_f]Anna[/name_f]!
She’s currently in my top three favourites for girls, and I just love her…simple, beautiful, classic, international 
And [name_m]Benjamin[/name_m] for a boy…also on my list. It’s classic and I love how strong it sounds!
