Death certificate? Thanks to a bit of sleuthing by SP staff - John Allan, stone dyker, 42 Murray Street, died 1 February 1909, wife Ann Low, parents David Allan, stone dyker, and Ann Grant, informant John Allan, son. I make that six major errors - given name, wife's surname, father's given name, father's occupation, mother's given name, mother's surname.
