Thanks, casalguidi for bringing my attention to this. Most welcome!
Wall family - I have a long screed of research info for you, but it's all relevant, so do bear with me...
Joseph James Cornhill was my 1st cousin 4 times removed - my 4th g-grandfather, William Cornhill b 1779 in Oare in Kent, was a serving soldier in the 7th Foot, and had two sons - William Jnr b 1826, from whom I descend, and Joseph b 1825. Both were born in Wokingham. William and Joseph spent most of their youth away from Kent, with their mother Martha in Wokingham, and did not return until about 1840 when their father left the army and returned to his roots in Faversham with wife and two sons, where he promptly died in 1841. (Martha had two daughters as well, whom she left behind in Wokingham, but that's another story!)
Joseph and William were both bakers. Joseph set up shop in Whitstable, William in Oare and Faversham.
Joseph James was the eldest son of Joseph and his wife Sarah Edenden/Iddenden, and was b about 1848.
He married Hannah Darby in 1868 - and she is almost certainly the lady you are looking for.
Joseph James and Hannah had several children, of whom John T was the last to be positively identified (via the census), b 1880 in Southwark. John T appears to have died in qe Sept 1883. However in qe March 1883 a Jessie Cornhill was born, who may have also been the child of Joseph James and Hannah. I have never sent for certificates to establish the child's father, but it looks probable.
Joseph James also had a brother, named Wallace. Wallace was also a baker and was living in London with wife Sarah Ellen nee Strong and 7mth old daughter Sarah in 1881. He returned to Kent, and in 1882 Wallace William was born - Wallace Jnr died in qe Dec 1883 in Medway district. Sarah his mother died shortly afterwards in qe Sep 1884 in Medway district.
Following these infant deaths and the death of Wallace's wife, both brothers disappear from England altogether, never to be seen again in the census or BMDs.
Joseph James's wife Hannah Cornhill (nee Darby) moved in with Lewis Golder and was living as his wife in 1891 and subsequent census returns. This can be positively established by the first names of the children listed as Golders that were actually Cornhills. I have never found a marriage, and still can't.
The child Ellen aged 4 and born in Herne Bay shown in the 1891 return is a problem child. An Ellen Cornhill was registered in Medway in 1886. An Elsie Golder was registered in Blean in 1886. In 1891 she is listed as Ellen b Herne Bay. In 1901 she is listed as Elsie b Herne Bay. So which one was she - Ellen Cornhill or Elsie Golder? Not sure it actually matters, to be honest!
The fact is that Joseph James Cornhill left his wife and children and went to Australia with his brother Wallace, probably in 1884. I have found no definite records of their emigration/immigration. But the subsequent records in NSW of the re-marriage of Joseph James (who declared himself a baker on the marriage cert) to Ada Roope/Rope in 1891 in Mudgee, NSW, and the records of his descendants, seem to indicate that he invoked the 7-year rule to declare himself free to marry, having already fathered at least three children with Ada. Wallace didn't remarry and appears to have died in 1902 in Gunnedah, NSW.
Joseph James's wife - Hannah Cornhill nee Darby - spent the rest of her life living with Lewis Golder as his wife, and bore him at least one child - Ellen/Elsie, born in 1886, long after Joseph James and Wallace had absconded.
Hannah Darby appears to have been the daughter of Edward (D?) Darby, a baker in Deal b about 1816, and his wife Mary (?) - see the 1861 census. She appears aged 10. At that time Edward and Mary had a 20 year old daughter so may have been married before 1841. All the family born in Deal.
Mistranscribed in 1851 as Edward Danby, baker employing 1 man in Deal - but there's Hannah at 7 months, wife's name confirmed as Mary Ann, and an eldest son aged 12, which pulls the likely marriage back to 1838 or before. Nothing on Free BMD for Darby or Danby and a Mary Ann, unfortunately. So it could have been pre-1837 or just never recorded, as registration was not compulsory during that period.
If you want to work backwards from Hannah, then parish records for Deal would seem to be the next step, to look for a marriage of Edward Darby (or perhaps Danby?) to a Mary Ann.
