Oh well found Mabel.
It does sound like good news for us. The plot dilutes!

The father George Edwards was supposed to be a "Gentleman's Gentleman"? and spoke various languages? The story goes that he left the family and Jane had to look after all the children by herself.

There is a rough settlement exam of Jane Edwards, age 33, in St Pancras in early 1861.
Sometimes these things can be a bit of a damp squib, but this one is crazy good

The gist of it -
Husband absent.
Says she was wed to Edward Edwards as Smithe spinster at Baden Baden, Germany, 3 March 1848.
2 children, Emma Jane, 6 years, and Louisa Anne, 3 months.
Husband left her in August 1860
He is a Servant. No relations. He was the illegitimate son of Lord Beresford and born in Waterford, Ireland about 45 years ago.
I am the daughter of John + Anne Smithe, both deceased. Father was a (small?) Farmer
I have an elder sister, Mrs Elizabeth Farrer (?), living at Sleaford, Lincolnshire, who could give more information
I was born (in?) Englefield Green, near Windsor.

There are certainly some similarities there to the family tales, even Windsor gets a mention!

Gro.Gov Records
Emma Jane Edwards 1853 Marylebone mother maiden name Smythe

Louisa Annie Edwards 1860 Pancras  mother maiden name Smythe

I am now thinking that the workhouse/school records could relate to the births flagged up earlier by Rosie. You have told us that there may have been an older sister Emma.
So here are the full details from GRO

EDWARDS, EMMA  JANE     
Mother's Maiden Surname: SMYTHE 
GRO Reference: 1853  M Quarter in MARYLEBONE  Volume 01A  Page 314

EDWARDS, LOUISA  ANNIE     
Mother's Maiden Surname: SMYTHE 
GRO Reference: 1860  D Quarter in PANCRAS  Volume 01B  Page 114

The mother of these two girls was Jane.
It looks like Jane and her daughter Emma were in St. Pancras workhouse in 1860. Records are on ancestry.
There were two successive admissions in October.
Jane Edwards 35
Emma Edwards 7
On the first admission Jane is described as Servant. On the second she is a Tramp.

In the workhouse Jane gave birth to a girl on 7 November 1860. This is the same birthday you have for your Louisa Annie, though the year is different.

Emma was sent to the school at Anerley on 19 November.
Jane (and baby as well, I guess) were discharged on 18 March (1861)

Meanwhile, curiously, there is a baptism (on ancestry) that gives the daughter's name as Jane.
5 December 1860 at St. Pancras, one of a number of workhouse baptisms that day
Jane
Parents Edward + Jane Edwards
Father a Servant
Abode Workhouse
Born 7 Nov 1860

One of the other workhouse baptisms that day was Rebecca, daughter of John + Mary Eliza Webb. Also born 7 November.
There is a birth reg for her as Rebecca Eliza Webb in Pancras, Dec 1860, 1b 114. That is the same GRO ref as for Louisa Annie Edwards. There is no birth reg of a Jane Edwards at that time in Pancras.

The Griggs appear on Wellington electoral rolls in the 1890's
For 1896 we have
Griggs, Henery Edward, Thompson street, Seaman's electoral right No. 1A issued
Griggs, Elizabeth Alice, Thompson street, married woman, residential
and in this year also
Edwards, Louisa, Thompson street, spinster, residential

This is about the time of the photo of Louisa Edwards and her niece Lousia Alice.
Henry Griggs is in the 1896-7 PO Directory at Thompson Street, not a vast number of other people listed there.
