Thank you everyone!
I do have the diary, but it is tiny, and often the writing is in pencil. There is one short line for each day, and lots of these consist of the weather, how well she felt, and any friends she sees.
The information I have about George Hogg, is mostly from my grandmother. We're sticking mostly to what her mother told her, but the plate-in-head story her grandmother told everyone DOES mesh with the gunshot wound to the head.
One of the entries in her diary is Monday 19 June: I go to Silkwood to see George.
Jean was sent up to Queensland for her health, where she worked, mostly in boarding houses and hotels. There are several references to her work: "General rows me in dining room" "Big crowd arrive" "Work day on... Very busy" "Go in the bar for first time" "Busy. Full house".
Lots of itinerant workers would travel up to Queensland to cut sugar cane. Hard work, but well paid.
I'll get that death certificate, and maybe the marriage cert too, and see how I go.
