Flagmaker Betsy ____ (4)
I believe the answer is:
ross
'flagmaker betsy' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ross that I've seen before include "Jonathan - - (TV)" , "-- And Cromarty, former county of Scotland" , "US singer Diana" , "Macbeth nobleman; Antarctic sea" , "Diana - (Supremes)" .)
