Very interesting thread!
I'm interested in where Pomeline comes from as well. I've done numerous searches throughout the years trying to come up with some etymological information on Pomeline and I've yet to find anything (like what it means, how it's pronounced...)!
As for Luana and Zaria, I like them loads. Not traditional royal names by any means, but they're steeped in mythology. Luana was used for a heroine in Romanian mythology while Zaria is the goddess of beauty in Slavic mythology. It seems Prince Friso and Mabel like names with mythological meanings.
Also, I saw someone in a pervious post mention Anastasia "Anna" von Vollenhoven. Her first name came from the fact that she was born on Easter and since Anastasia means "resurrection", her parents thought it an appropriate name to use.
I thought I would add here, too, that Pablo Urdangarín's second name, Nicolás, comes from the fact that he was born on St. Nicholas's feast day, December 6th.
Other names I've wondered about are (in bold print):
Felicia von Vollenhoven
Zenouska Mowatt
Countess Luana's secondary name,
Ninette
Isabella Lily Juliana von Vollenhoven
Lady
Kitty, Lady
Eliza Victoria, Lady
Katya Amelia,
Louis and Lady
Lara Spencer
Maria Carolina de Bourbon-Parma, daughter of Princess Irene
Princess
Elisabeth of Hesse-Darmstadt, daughter of Ernst Ludwig and Victoria
Melita
Eloise and
Estella Taylor
Lady
Davina Lewis
Countess
Leonore Marie Irene
Enrica
Also, why is it that the older Spanish grandchildren, Felipe, Victoria, Juan and Pablo have secondary names (in addition to "de Todos los Santos"), but Miguel, Irene and Leonor (and probably the new little Infanta, as well) don't?
