Girl rising in the morning the day before (5)

I believe the answer is:
maeve
'girl' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'rising in the morning the day before' is the wordplay.
'rising' is a reversal indicator (going up in a down clue).
'in the morning' becomes 'am' (AM on a clock).
'the day' becomes 'eve' (eve is a kind of day).
'before' says to put letters next to each other.
'am' after 'eve' is 'eveam'.
'eveam' written backwards gives 'MAEVE'.
Can you help me to learn more?
(Other definitions for maeve that I've seen before include "__ Binchy, Irish novelist, d. 2012" , "Name" , "Irishwoman" , "Novelist Binchy or old Celtic Queen" , ". . . . . Binchy is popular novelist" .)
