To bring the thread up to speed: through PMs (due the recent nature of the events), the link to the Dickens family has been established via the marriage of Frank Bliss and Edith Kate Dickens in 1899
21 May 1899 St Mary, Willesden
Frank Bliss / 21 / bachelor / painter / 46 Brownlow Road / Mathew Bliss / Painter
Edith Kate Dickens / 19 / spinster / 46 Brownlow Road / John Dickens / labourer
The 1911 census gives birth places for both of these people as Stewkley, Bucks.
I suspect that Annie Dickens was born Jun qtr 1898 Wandsworth 1 d 609, and appears on the 1901 census with her grandparents in Great Brickhill, Bucks:
THomas Dickens Head Mar 64 Labourer bn Stewkley
Jane Dickens Wife Mar 66 bn Gt Bricknell
Chas Dickens son single 27 Labourer bn Gt Bricknell
