Anecdotalist (9)
I believe the answer is:
raconteur
'anecdotalist' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for raconteur that I've seen before include "one with a gift for relation" , "source of stories?" , "He's good at telling stories" , "Teller of anecdotes, Frenchstyle" , "Narrator" .)
