Yokels displace family with son (8)

I believe the answer is:

bumpkins

'yokels' is the definition.
('bumpkin' can be a synonym of 'yokel')

'displace family with son' is the wordplay.
'displace' becomes 'bump' (synonyms).
'family' becomes 'kin' (synonyms).
'with' says to put letters next to each other.
'son' becomes 's' (genealogical abbreviation for son).
'bump'+'kin'+'s'='BUMPKINS'

(Another definition for bumpkins that I've seen is " from the country".)

I've seen this clue in The Times.
