4 year advance sounds good.
From your list, I would be happy to use:
Agatha
Josephine - Zéphine can be a nickname
Naomi
Cecilia - Celia is also nice.
Oriana
Penelope
Gideon
Jude - as mn
Vincent
(Yeah, I'm picky with boys' names).
So, a combined list:
Agatha
Astrid
Catherine - mn
Cecilia
Elaine - mn
Josephine
Margery / Marjorie
Muriel
Naomi
Oriana
Penelope
Rosamund
Saskia
Tabitha
Tallulah
Veda
Dorian
Gareth
Gideon
Jude - mn
Llewellyn
Lysander
Malcolm
Marius
Vincent
EDIT: I'll post this as finished.
