Noted first name in jazz (4)
I believe the answer is:
ella
'noted first name in jazz' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ella that I've seen before include "Great late jazz singer . . . . Fitzgerald" , "- Wheeler Wilcox, US poet" , "- - Fitzgerald (mus.)" , "Girl" , "---- Fitzgerald, 'Queen of Jazz'" .)
