Crusoe's strange origins (7)

I believe the answer is:

sources

'origins' is the definition.
('source' can be a synonym of 'origin')

'crusoe's strange' is the wordplay.
'strange' indicates an anagram.
'crusoes' anagrammed gives 'SOURCES'.

(Other definitions for sources that I've seen before include "Origins or derivations" , "Informants" , "Points of origin" , "Places of origin or reference" , "Starts" .)

I've seen this clue in The Telegraph.
