Here is an excert from E. Walford's. "Greater London". Vol. 2, Fo. 104:-
"The family of Attwood, by whom Standerstead Court was built, had long been seated in that Parish. Mr Levison-Gower says : 'In a fine of land relating to Standerstead, 19 Edward III., I find the name of peter Attwod; and in Coulsdon, the adjoining Parish, the same name occurs in 6 Edward II., when eter Attwood and John and Roger De Bosco (or of the wood), are returned as owing lands in that Parish. their name is still retained in Wood Place in Coulston. Over the house at Standerstead Court is a shield with the arms of Attwood, a lion rampant between three acorns, surmounted by their crest, a woodman's axe."
