Excellent work everyone. I am still convinced that is Eleanor pretending to be Mrs. Graham.
That Millis/Esberger link I'm following up. It could be the missing link. I have traced a lot of the Millis' but I'm stuck with John Robert Millis.
I have this information:
John Robert Millis, born circa 1787 and buried 6 August 1849 at Pentonville Chapel, St. James, Clerkenwell, London.
He married 1stly to Lydia Brime on 9 February 1809 at St. Bride, Fleet Street. They had a daughter Edith Sarah Millis (she married Francis Bult Dunstan on 1 March 1840 at St. Clement Danes, London -- they had 3 sons).
It seems there could be two John Millis', because John and Lydia have further children after 1822
He married 2ndly to Elizabeth Fortye Maunsell (born 28 March 1798, Fremington, Devon; died 27 June 1853, Coppice Row, Clerkenwell and buried 4 July 1854 at Pentonville Chapel -- she was the daughter of Thomas Ridgate Maunsell and Maria Fortaye Daly) on 30 November 1822 at St. Bride, Fleet Street, London. They had 7 children, including Eleanor Sarah Fortye Milllis.
So the Mary Millis who married Henry Esberger could be a sister of the above John Robert Millis. Can anyone mayhaps check this?
Emily Esberger married Frederick Belford at St. Paul, Hackney on 31 December 1871. She's indicated as the daughter of Thomas Esberger, a Beer-Retailer. Frederick Belford is son of Thomas Belford, a Nautical Instrument Maker.
I am not sure if that will help locate Eleanor in a later census or not though. I still suspect that death Ruskie found for an Eleanor Millis could be her.
Addendum: It seems Thomas Esberger married again on 22 September 1870, at St. John at Hackney, London, to Hannah Furneaux (née Baylis). He was a widower and son of Michael Stephenson Esberger (he also married in London), a warehouseman. Thomas is a Beer-Retailer.
Hannah Furneaux was a widower and daughter of Cornelius Baylis, a Market Gardener. Coincidently, she is of Loddiges Road, which I have come across before (but I need to look up where).
This, of course, is not Annabel either. Is this mayhaps his third wife, therefore?
