Axelina is of course the female form of
Axel. She would probably be nn
Lina.
I think
Alexina is a fresh alternativa to other Alex-names.
I like
Alexina Fleur or
Alexina May.
"You may give them your love but not your thoughts. For they have their own thoughts.
You may house their bodies but not their souls,
For their souls dwell in the house of tomorrow, which you cannot visit, not even in your dreams."
(On Children by Kahlil Gibran)
