Loving the name “Eirlys” for a little girl. Eirlys is of Welsh Origin and means “snowdrop”. This is a family honour name on my dh’s side.
Pronunciation: [name_f]Air[/name_f]-Liss
(Pls suggest name combos)
It’s a beautiful name! I would suggest a simple middle name for such a unique first name.
If you wanted to stick with something Welsh, you could try Eirlys [name_u]Bryn[/name_u]
It’s unique (at least in my area) but kind of refreshing. I like it!
I think that Eirlys will get mistaken for [name_u]Ellis[/name_u] a lot.
Eirlys is lovely! If ever a name was fit for a fairy, it was Eirlys. I have a special attachment to snowdrops, so I would definitely use it.
I think you could go many different ways for a middle name, from the elegant and polished (Eirlys [name_f]Celeste[/name_f], Eirlys [name_f]Lucina[/name_f], Eirlys [name_f]Sybilla[/name_f]) to the more down-to-earth and tomboyish (Eirlys [name_f]Meg[/name_f] or Eirlys [name_f]Maddie[/name_f] for instance). It just depends on your taste. 
Yes yes yes!
In theory I like it, but I think the spelling will lead to a lot of pronunciation issues.
