Somehow trace son and parent? (8)
I believe the answer is:
ancestor
'parent?' is the definition.
(parent is a kind of ancestor)
'somehow trace son' is the wordplay.
'somehow' indicates an anagram.
'trace'+'son'='traceson'
'traceson' with letters rearranged gives 'ANCESTOR'.
'and' acts as a link.
(Other definitions for ancestor that I've seen before include "Predecessor" , "Adam was our first one" , "Enactors (anag)" , "Old member of the family -no traces (anag)" , "Person from whom one is descended" .)
