Eloise is fabulous. Would May be the mn? I'm not sure about May with Moore. I think someone on here had an Eloise Angelica, which is stunning. Food for thought.
Faith Lyla sounds nice, but bear in mind she will sometimes be 'Moore, Faith' as in 'more faith', so you need to decide if you mind.
Tiana's ok. Is Amily a typo for Emily, or do you mean Amelie? Or Or even Amity?
I tend to think of Riley as a boy's name, but it's the name of the girl in Inside Out, so I guess it's crossing over.
Niyyah- do you have Muslim heritage?
Julielle- never heard of it. Sounds a bit of a clumsy mash up of Julie and elle. Julia? Juliet? Juliana? Julienne? I'd avoid Julianne for the actress.
Aliana- another that sounds made up.
Leah's a lovely name, and not too popular. It would take any style middle name, but I'd avoid anything ending A. Leah Jane, Leah Grace, Leah Catherine, Leah Meredith, Leah Rosalind, Leah Seraphine, Leah Robyn, Leah Antigone- whatever floats your boat.
Eloise May: that's nice, I prefer Elodie or Eliza, but it's a perfectly fine name. Faith Lyla: I don't like Faith but I do like Faye? Lyla Faith? Laila Faith? Tiana Amily: Tiana is a bit princessy. I really like Amity Riley: I don't like it, Niyah: I don't like that either Julielle: I prefer Juliette, Julie or Julienne Aliana: looks a bit made up but is nice. Do you like Ariana, Anita, Alanna or Alina/Aleena? Leah (too common?): it's fine.
