My great grandfather...
died 6th November 1936
aged 74 Frank Brettell is also my great grandfather and the added information I can give you is that one of his obituaries mentions that: They laid him to rest on 9th November at St Paulinus Churchyard, Crayford, a wreath being sent on behalf of the members of the V.C.D. Athletic Club. - possibly if you could find a way of reading the headstone in that churchyard you would have the exact birthdate.
