An interesting list.
Aurelio and
Silvio are fine names even though it's more common to see the female versions
Aurelia &
Silvia.
Even though Isandro is a form of Isander/Isandros, it looks like
Lisandro with the "L" missing.
I think
Nereida is pretty. I like the "sea nymph" meaning and the mythological connection.
I believe
Dayana is a form of
Diana and Isela is taken from
Marisela.
