A tempestuous character, mother pocketed R1 (7)
I believe the answer is:
miranda
'a tempestuous character' is the definition.
(character in Shakespeare's The Tempest)
I don't understand the rest of the clue.
(Other definitions for miranda that I've seen before include "Female in The Tempest" , "Heroine of The Tempest" , "girl" , "Prospero's daughter (Tempest)" , "Prospero's daughter (The?Tempest)" .)
