I thought I would update everyone who tried to help me find this family!!!
I today received Eliza's will dated 30 Nov 1917, probate granted 18 May 1922].
It names son Percy Lionel Cohen as executor, & daughters Katie Louise Smith, Maud Mary Dale, Ella Baker, Violet Clough, Mabel Eva Owen & daughter in law Elizabeth [Lillie] Cohen as beneficiaries. Unfortunately no addresses for any of them, so don't know if any of them were in Australia.
I didn't know of children Violet, Mabel Eva & Percy Lionel as children so almost more questions than answers. Eldest daughter Eva Eliza born 1865 is not named.
I have found a birth for Percy 1873 Q1 St Pancras 1 b 151; possible births for Mabel Edith 1875 Q1 Islington 1 b 388 & Mabel Lena E M 1877 Q4 Hackney 1 b 469; possible birth for Violet 1884 Q1 Islington 1 b 296; marriages for Percy Lionel to Elizabeth Sakin 1897 Q3 St Giles 1 b 1290, Violet to James Wallace Clough 1904 Q4 St Giles 1 b 1039 & Mabel to Francis Harry Owen 1906 Q4 Hastings 2 b 37.
However just as before with mother ELiza & the elder daughters, I have struggled to find these previously unknown children on the 1881 & 1891 censuses. I feel they must have been out of the country, possibly Australia [as Australian papers were mentioned in Eliza's obituary] or India [where Eliza married, & the first 2 daughters were born & Lionel the father had had a business with his brother Frederick] - perhaps there were still connections.
Anyway the search goes on.....
