You mix
Nerissa and
Melissa and get a new name: Nelissa
But if it is your own daughter's name, you must where you got the name from.
"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)
