Crossword Genius

For the family, make an effort (6)

Ross

I believe the answer is:

strain

I believe this clue is a double definition.

'for the family' is the first definition.
(thesaurus)

'make an effort' is the second definition.
(I've seen this before)

(Other definitions for strain that I've seen before include "Family - tension" , "Filter the stress" , "Stretch or exert to the utmost" , "Remove by passing through a filter" , "Wrench; melody" .)

I've seen this clue in the Evening Standard.
