Generous ruddy family (7)
I believe the answer is:
kindred
'family' is the definition.
(kindred means one's relatives)
'generous ruddy' is the wordplay.
'generous' becomes 'kind' (similar in meaning).
'ruddy' becomes 'red' (synonyms).
'kind'+'red'='KINDRED'
(Other definitions for kindred that I've seen before include "Family and relations" , "Relatives" , "Relationship by blood" , "Closely related" , "Associated - relations" .)
