Told of a family connection? (7)
I believe the answer is:
related
'told' is the definition.
(as in relating a story)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for related that I've seen before include "Narrated; connected" , "Kindred" , "within family" , "Family members must be" , "Connected by family ties" .)
