Uncle perhaps? That would be telling (8)
I believe the answer is:
relation
I believe this is a double definition.
'uncle perhaps?' is the first definition.
(I know that uncle is a type of kinsman)
'telling' is the second definition.
(to relate a story can mean to tell it)
'that would be' acts as a link.
(Other definitions for relation that I've seen before include "Story-telling - member of the family" , "Reference" , "Kin" , "Oriental kind of family connection" , "Account" .)
