I had an aha moment when I got to this combo - [name_f]Eira[/name_f] [name_f]Nyx[/name_f]. I love [name_f]Eira[/name_f] (meaning: snow), but feel it needs a punchy middle. I eventually got to [name_f]Nyx[/name_f] (meaning related to night). I’m really digging the imagery: snow, night, winter’s night.
What do you think? Over the top maybe? It’s on the list for now though 
Well, I think [name_f]Nyx[/name_f] is gorgeous and totally usable as a MN, especially with the Welsh FN, but given my signature I might be a little biased 
I think it’s fine. I doubt many people would make the snow/night connection, but I do think it makes a good imagery too. I love [name_f]Eira[/name_f] (as ay-ruh) and [name_f]Nyx[/name_f] is so cool, I love the mythology and nature connection. [name_f]Nyx[/name_f] is an awesome sounding name I think makes a great middle.
[name_f]Eira[/name_f] [name_f]Nyx[/name_f] is so beautiful, and I love the meaning and imagery!!! I don’t see why it wouldn’t be usable, honestly. I say go ahead if you love it! 
Yes usable- Pretty as well.
Totally usable! Very obviously Welsh but also carries the magical feeling into English and is easy to pronounce and spell etc.
A really great name.
Awesome names and totally usable!
Actually, I first saw [name_f]Nyx[/name_f] on your signature ages ago and haven’t stopped thinking about it! [name_f]Hope[/name_f] it’s ok that I “borrowed” it :). [name_u]Love[/name_u] your combos!
Thanks everyone, glad to hear the positive reactions. It’s not often that a combo just falls into place.
Definitely usable. [name_f]IMO[/name_f] almost any middle name is usable and [name_f]Eira[/name_f] is beautiful.
