First, I want to tell you how amazing your style is and how beautiful your daughter's name is.
As soon as I saw your boys list, I loved these names with your daughter's:
For some reason, I LOVE Endymion or Aurelian with Aphrodite, so these came to mind:
Aurelian Basil Oliver
Aurelian Faulkner Basil
Aurelian Osiris Hugh
Endymion Faulkner Hugh
Endymion Lawrence Antony
Endymion Gareth Tiberius
I don't know, I struggle with flow XD
However, since your daughter's name starts with an A, will you be willing to repeat first initials?
Can't wait to see the rest of this little baby's naming journey!
I think the same thing is true here-- I would studiously avoid a Greek name, particularly a mythological name, for the second baby, else again the pairing loses some of the magic and starts to look a bit thematic. Again, for future children I absolutely think names like Endymion would be back on the table... just not right away with Aphro-D. I included Romulus too in the strike-list since it's so obviously mythological.
Aurelian (very classical)
Evander (also Scottish)
Hadrian (again, classical)
I think I am on the fence about Auberon, Herne and Gawain as well, as again they might match Aphrodite too well. Maybe not though (esp Herne as it is so much less well-known).
My favorites for the sibling pairing are the unexpected ones: Laszlo, Faramond, Rainier, Casimir. So very different yet equally striking, original & bold style statements.
