At the 1901 census she was living with her parents at 393 Holloway Road, Islington, London, aged 17.

There are two Edith M Hoare births on FreeBMD for 1883-4:

Births Sep 1883  HOARE  Edith Maud  Holborn  1b  747
Births Sep 1884  Hoare  Edith Mary  Staines  3a  5

I incline to the first of these.  Other evidence confirms this.

Her parents were still there in 1911 but she wasn’t. She had just married:

Colburn Arthur J Islington 1b 255   
COLES William P Islington 1b 255

And she m. Wm Coles.  But later formed a liaison with a chap called Ogilvie (sp?) who fixed her up with a flat somewhere in London.
