It's a Welsh name - I knew someone called this. It's pronounced eh-LE-ri and it's definitely for a girl. In Welsh I don't think there's another way of spelling it. A middle name that's also Welsh would be good, like Carys, Ffion, Bethan, Rhiannon, Angharad or Seren. I like it. It's not common even in Wales (I only knew one girl with this name), but it's pretty.
I don't really like it. It looks too trendy for my taste.
It's okay... it just sounds like you're missing a C at the beginning though and you're supposed to say celery.
I don't like it. Sounds like celery.
BQ4: Elery Grace
BQ3: girl, although I think it's "classified" as a boy's.
BQ4: Ellery Madeleine [or Ellery Xander for a boy].
I don't like it. It's very cutesy and sounds too similar to 'celery'.
BQ4: Something more traditional, perhaps Ellery Catherine or Ellery Caroline.
It looks like the name Ellery which I don't like because it sounds like celery. However this is a different name: http://www.behindthename.com/name/eleri and it is pronounced "e-leh-ree" however if you live in an English speaking country it will just be pronounced ellery which is an ugly boy's name that sounds like a girls name that also sounds like a vegetable.
