I am getting the feeling I am just not meant to trace this family....
Just heard back from researcher about Dependant Children's REgisters- the registers for the Creighton children has not survived and there are no alternative records that might tell me what happened to the children or if they eventually were returned to their mother.
Coonabarabran parish has discovered they do not hold the PR's back as far as 1875, Coonamble do not have registers for that time, and the diocean office advise if the local parishes do not have the PR's then they may have been lost.
No luck with chasing for access via Dept of Corrective Services to Coonamble gaol records to see what is reported of Esther there.
COntacted National Library who hold newspapers for that region- but not back as far as the 1880's- they have suggested contacting State Library.
Inspiration anyone?
