Her father could be William McCracken born in Scotland, 1861 and mother Margaret also born in Scotland, 1871 ... last count was 1891 census in Scotland, they had a son John McCracken, born 1891 in New Cumnock, Scotland, have not been able to find them in Scotland for 1901 census
If anyone has access to the 1901 English census I would be most interested to see this 1901 census with Susan Muir McCracken and her parents
