Boy or girl's name (3)

'boy' is the first definition.
'girl's name' is the second definition.
(Other definitions for mel that I've seen before include "- - Gibson (actor)" , "Honey" , "-- Brooks, film director" .)
(Other definitions for val that I've seen before include "girl" , "- Kilmer, US_actor" .)
