Please, please, please do not change the spelling of a name, use the traditional spelling, any other approach corrupts the name.
I think that a name with an L in it like Willow would make a good fit otherwise I think that Laurel would be very sweet and lovely.
your 'variations' on spelling may not cause pronunciation problems BUT THEY CAUSE SPELLING PROBLEMS.
PEOPLE WILL ALWAYS BE SAYING L-U-N-A & A-R-I-A AND YOUR CHILD WILL BE SAYING NO, THERES RANDOM U'S AND Y'S
please dont do this.
I read on-line that Louna is the French spelling of Luna. Is it really that bad to spell it differently?
Laurel is lovely and I'll definitely add this to my list.
I think Aria is too close to my own name and have heard it being pronounced on tv recently as A-ree-ahh which isn't the way I thought it should sound!
I'm not really any further forward though even with everyone's suggestions! :confused:
I love Luna. Louna looks like the first syllable could be mispronounced like loud. I wouldn't but I think a lot of people would. Other less common names you might consider for girls:
Alla (too close to your/ Lillia's names?)
Zelig (random but rare and with an L sound)
Leo (popular but a great name)
I have no idea how to pronounce Auria. I would try to put the u sound in there and pronounce it like Autumn.
I am not the biggest fan of fancy spellings so I am not a fan of your top two.
I do like Aria and Luna is fine.
I also like:
Lyric (goes with the musical theme from Aria)
Lyra (pronounced quite differently from Lyric and is also musical an old-time instrument)
Lincoln was the first thing to come to mind
Sorry if I am repeating...
Helene / Helina
Juliet / Joliet / Juliette / Joliette
I like Luna and prefer Lachlan spelled like this. I prefer Aria spelling, then Arya like the GoT character. Ariah makes me question the pronunciation...as in "Is it like Uriah?" Arya was on the top of our girls list until Game of Thrones TV version blew it up; we worry about the trendiness now.
P.S. if you're not already aware, opening Super Search and looking for L names can be really helpful. You can specify popularity and other things.
