I've had a fresh look at Eliza Jane and this is what I know for sure:
Birth registered Sep qtr 1859 St Saviour, Southwark mmn CRISPIN
Parents were William BOWBRICK (1831-1906) and Elizabeth CRISPIN (1823-1889)
Appears on censuses 1861-1871 in Southwark with parents and siblings
Not found on 1881 census (neither are her parents - are Southwark pages missing?)
Appears on 1891 census in Southwark as wife of James A BOONE with children Harry 13, Ellen 8, George 7
Not found on 1901 census
Marriage 2 Mar 1905 Walworth Surrey to John GOULD
1911 census - Eliza GOULD, widow, living with daughter Maggie wife of Thomas BOND, and daughter Teresa BOONE
Probable death 1920, Islington
BOONE mmn BOWBRICK children found on GRO are:
Ellen (1884 St Saviour) possibly m1907 Southwark to William John O'CONNOR
James Alfred (1886 Greenwich) d1888
Charles William (1888 Camberwell) d1890
Margaret Amelia (1892 Camberwell) m? Thomas BOND, alive in 1911
Theresa (1894 Camberwell) alive in 1911
Emily Catherine (1895 St Saviour) alive in 1911
Mary Ann (1897 St Saviour) d1899
Emily (b1885) is on the 1911 census with widowed aunt Theresa BOWBRICK.
I haven't found a marriage of Eliza to James BOONE, nor have I seen an obvious death on FreeBMD for him (If James' age of 39 on the 1891 census is correct, the death of James BOONE aged 40 in Shoreditch in 1898 may not be him)
There are a couple of possible deaths on FreeBMD for John GOULD between 1905 and 1911.
Of the children on the 1891 census, Harry may not be Eliza Jane's child, Ellen definitely is, but I'm not sure about George (perhaps his birth was not registered).
