There's an Emily Shoesmith death record in Fylde in 1940 aged 50. This looks likely, given the place of marriage and Fritz's death in Blackpool a decade later. It would place Emily's birth year at c1890
In 1901 in Blackpool there is the following:
Joseph William Blackburn 26 Stoker at Electricity Works Cornholme, Yorks
Mary H Blackburn wife 26 b Mytholmroyd? Yorks
John J son 3 Kirkham, Lancs
Elizabeth Lord Mother in Law 63 Holmforth, Yorks
Emily Lord Neice 10 Cornholme, Yorks
Plus a boarder
in 1891 in Todmorden (the nearest town to the tiny Cornholme)
James Lord 28 Cotton Warehouseman Todmorden, Yorks
Emma Lord 31 Do Lancs (clearly an error on place or county)
Thomas 3 Todmorden
Emily 1 Todmorden
There's an Emily Lord registered in the Todmorden district in Dec 1890, which looks a good match
