Hospital record
28 Jun 1862
Melbourne, Victoria
Discharged 11 Jul 1862
Patients in Melbourne Hospital 1856-1905I would suggest that after reading Thomas's death certificate on a public tree that it is possible the Police Constable at the inquest into his death, has confused Ann's surname
STAFFORD with the county Staffordshire in England. Information on death certificates is unreliable and especially if given by someone who is not family. On the issue column under children's names...deceased 1 particulars unknown. If Ann had been giving the information she would have known the name of the deceased child....so who gave Thomas's and Ann's details to the PC?
Thomas injured his foot and died from the infection in hospital. The Police Constable attending the inquest was the informant on the death certificate.

Cause Pyaemia
It would be interesting to see the parental details on the other birth certificates especially the date of their marriage

.
I wonder what marriage info is on this cert - possibly not accurate anyway. Strange that family wouldn't know her maiden name.

Assisted Immigrant Arrivals
http://prov.vic.gov.au/index_search?searchid=24STAFFORD Anne 24 years arrived 3 Nov 1854 on the
APOLLINE Book 11 Page 105 - another resource shows her place of birth as Fermanagh; Religion Church of England and she could only read not write.
STAFFORD Ann 25 years arrived 2 Sep 1857 on the
HORNET Book 13 Page 28 - another resource shows her place of birth as Middlesex; Religion Church of England and she could read and write. Disposal List shows she was employed by Mr
WILSON of Studley.
That places her in the area of her first birth, Annie Elizabeth, at Kew in Oct 1858.
