The Land of Nowhere

Cool! Unfortunately, she doesn't seem to be on FindAGrave (there's a different Elizabeth Sheppard in the cemetery, who was married and died in 1914). I did get her burial info from deceasedonline.com, which says that she was buried in square 18 in grave #7969, but it doesn't look like that's easy to locate and the marker may not still be there.

(Having fallen this deep down the whole, I might contact Friends of West Norwood Cemetery to see if they know anything, though!)
