I read an article the other day about a family that had 4 children named after the astrological 4 elements: [name]Earth[/name], [name]Fire[/name], Water, [name]Air[/name]. So each child had a water, fire, air, or earth themed name. And I thought it was such a cool idea. What would you use?
Girls:
[name]Terra[/name]
[name]Ember[/name]
[name]Brooke[/name]
[name]Windy[/name]
Boys:
[name]Stone[/name] or [name]Canyon[/name]
[name]Aidan[/name]
[name]River[/name]
[name]Blue[/name]??? Can’t think of a good one for [name]Air[/name].
You could also use the names related the zodiac, which is divided into elements:
[name]Fire[/name] (Ares, [name]Leo[/name], Saggitarius)
[name]Mars[/name]
[name]Lionel[/name]
[name]Archer[/name]
[name]Earth[/name] ([name]Taurus[/name], Virgo, Capricorn)
Byre
[name]Virginia[/name]
[name]Caprice[/name]
[name]Air[/name] ([name]Gemini[/name], [name]Libra[/name], [name]Aquarius[/name])
[name]Gemma[/name]
[name]Liberty[/name]
Arius
Water (Cancer, [name]Scorpio[/name], Pisces)
Crabby (joke)
[name]Pio[/name]
[name]Fisher[/name]
When I first read your post, I thought that they actually named them [name]Earth[/name], [name]Air[/name], Water and [name]Fire[/name]! I am glad that it was just a themed name. I think it is a sweet idea, especially if you are a very at one with nature sort of couple, and do plan to have four children. The only problem would be if the connections were too obvious and they sounded like a family of superheroes!
I would use :
Girls :
[name]Fiammetta[/name] [name]Shula[/name] nn [name]Fia[/name] - fire (Italian and Arabic names)
[name]Nephele[/name] [name]Sora[/name] nn [name]Ellie[/name] - air (Greek ‘cloudy’ and Japanese ‘sky’. Actually, that isn’t a great combinied meaning …)
[name]Demeter[/name] [name]Ila[/name] nn [name]Demi[/name] - earth (Greek and Sanskrit)
And one boy :
[name]Rio[/name] [name]Merlin[/name] - water (Spanish and English/Welsh).
What a lovely idea, i think you could get away with it if you did it subtly! I would go for-
[name]Air[/name]- [name]Skye[/name], [name]Storm[/name], [name]Blue[/name], [name]Aura[/name], [name]Era[/name]
Water-[name]River[/name], [name]Isis[/name], [name]Ocean[/name], [name]Rio[/name], [name]Azura[/name], [name]Raine[/name], [name]Tallulah[/name]
[name]Fire[/name]- [name]Burney[/name], [name]Blaise[/name], [name]Nina[/name] (Native American origin also apparently)
[name]Earth[/name]- [name]Isla[/name], [name]Everest[/name], [name]Nevis[/name], [name]Ila[/name], [name]Terra[/name], [name]Sandy[/name], [name]Savannah[/name]
I think its a really sweet idea to have some kind of connection between names, also it makes it special for the siblings to have a connection.
I could totally see myself doing this! With some difficulty to say the least… Here’s all names with the right meaning, but I’d never go all out like this myself. Fiammetta is a long time love of mine ^^
[name]Fire[/name]: Fiammetta Brighid [name]Hestia[/name] nn [name]Etta[/name] or [name]Fia[/name] and [name]Ignatius[/name] [name]Ronan[/name] [name]Elmo[/name] nn [name]Elmo[/name]
Water: [name]Mayim[/name] [name]River[/name] [name]Ondine[/name] nn [name]May[/name] and [name]Caspian[/name] [name]Jules[/name] [name]Merlin[/name] nn [name]Ian[/name]
[name]Earth[/name]: [name]Cressida[/name] [name]Sylvie[/name] [name]Demeter[/name] nn Cress and [name]Hermes[/name] [name]Peter[/name] [name]Everest[/name] nn [name]Mies[/name]
[name]Air[/name]: [name]Inanna[/name] [name]Starling[/name] [name]Isis[/name] nn [name]Annie[/name] and [name]Heron[/name] [name]Zephyr[/name] [name]Storm[/name] nn [name]Ron[/name]
Okay, this was hard… I should have dropped the second middle.
Kudos to those who know what I’m thinking on all of these names, [name]Cressida[/name] and [name]Jules[/name] especially are somewhat obscure in their relationship to earth and water… 
Oh, I can’t believe I forgot [name]Ondine[/name]/[name]Undine[/name]! It has been on our list (well, DH said only for a middle) for so long.
Girls:
[name]Makani[/name]
[name]Gaia[/name]
[name]Moira[/name]
Pyrrha
Boys:
[name]Zephyr[/name]
[name]Clay[/name]
[name]Kai[/name]
[name]Blaise[/name]
This is actually a little tangential, but I know a family who has 4 boys. Their names are [name]Ocean[/name], [name]River[/name], [name]Sky[/name] and [name]Canyon[/name].
If I did something like this the names would be more like…
Direction~ [name]Atlas[/name], [name]East[/name], Climb
Weather~ [name]Raine[/name], [name]Sky[/name],
[name]Earth[/name]~ Creeke, [name]Day[/name], [name]Leaf[/name],
Feelings~ [name]Hope[/name], Thought, Dare, [name]Dream[/name], Silent
Place~ [name]Bay[/name], Mountain, Wander, Place
—What do you think? I like some but, then again…
I would use [name]Ember[/name]/[name]Brooke[/name] or [name]Aidan[/name]. What about [name]Skye[/name] for [name]Air[/name]?
[name]Male[/name] then female selections
[name]Air[/name]: [name]Zephyr[/name], [name]Azure[/name]
Water: [name]Kai[/name], [name]Maya[/name] (Hebrew for water)
[name]Fire[/name]: Cinaed (born of fire in Gaelic), [name]Azar[/name] (fire in Persian)
[name]Earth[/name]: Riku (land in Japanese), [name]Ila[/name] (earth in Sanskrit)
Mine would be:
[name]Earth[/name]: [name]Demetria[/name] “earth mother” and [name]Adam[/name] (created from the earth)
Wind: [name]Brisa[/name] “wind” [name]Zephyr[/name]
Water: [name]Rosemary[/name] “dew of the sea” or [name]Galina[/name] (from goddess of calm seas) [name]Calder[/name] “rocky waters”
[name]Fire[/name]: Fiametta “fire” and [name]Fintan[/name] “white fire”

When I first read this I thought you meant the scientific elements. I do admit to falling asleep in Chemistry class but then I found that if I looked at the periodic table then I could imagine what strange family would call their children after elements and what their nn would be. I then found myself making sibsets out of them! Oh the thoughts that come out of boring lessons!!!
