Iris Ophelia Camille - Iris Ophelia is gorgeous, so is Iris Camille, however, Camille doesn’t do much for me in this 3-name-combo, it’s a lovely name but it doesn’t get enough room to shine next to Ophelia. Iris Ophelia Mae would be wonderful, Iris Ophelia Sophie would be super sweet, too.
Elodie Viviana Mae (or Elisabeth Viviana Mae?) - First, I love long names. Still, this feels too long as it doesn’t roll off the tongue. I think Elodie and Viviana are beautiful names but they don’t work well together. That’s not to say Elodie doesn’t work with a 4-syllable name but I think the emphasis lying on the 3rd syllable of Viviana makes the whole combo feel super long (opposed to e.g. Elodie Cornelia Mae or Elodie Elisabeth Mae - same # of syllables but a different emphasis).
Aurora Thessaly Frances - All three names are lovely, the flow is great, too. Personally, the names are not ones I’d pair together but the more I look at the combo the more I like it.
Primrose Emiliana Sophie - same as with #2. The combo just feel very long due to the extra -ana part. Rose Emiliana Sophie would be gorgeous, same with Primrose Emilia Sophie or Primrose Viviana Sophie/Mae.
I hope I didn’t come off as too negative, that really wasn’t my intend as you have so many wonderful names in these combos.
