Thompson of "Creed" (5)
I believe the answer is:
tessa
'thompson of creed' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tessa that I've seen before include "Girl's name; former savings account" , "Girl's name, forerunner of ISA" , "Girl" , "Dahl or Jowell" , "Woman" .)
