Many thanks to you both, MaureeninNY and Girl Guide.
Regarding that crew list to Honolulu, on that day Albert was among the crew of the WYRUMA between Melbourne and Sydney. I would still like to see that crew list mentioned - "page starting Bearup" - just in case it gave a clue to anything else, but unfortunately couldn't find it in Ancestry, even though I have a Worldwide membership.
I have been investigating several other weddings (remember it's Albert Ernest Hammond) and looked into Mary Ellen Lynch, Victoria, 17 May 1907 (newspaper announcement makes it clear that his father was local); Alice Gillingham which is not his wife; and a Louisa Hammond living with an Albert Ernest Hammond on a subsequent Electoral Roll in Victoria, again it doesn't check out.
If I give some extracts from his final, rather desperate, letter dated 12 September 1916, it may give a better idea of his state of mind. It is clear that he was not on the journey he mentions, and he seems to have little knowledge of Canada, and I haven't found any army/navy service record:
“Good Bye Sydney!”
"I have tried everything, hotels for instance, here in New South Wales and there is no employment for me. So I have decided this time to leave the country and go to Canada. I am tired of Australia where is no money to be made, and money I want, I must have.
I am leaving this week for the States and don’t know how things will there with me over there when I arrive. If things are no different I will join the unfortunate devils in the war.
I received a letter from you this morning demanding money from me, it’s is no use you writing to me in that strain. If I don’t earn it you can’t get it.
I expect I will settle in a place called in Canada Ontario. Times have changed, I’m not the same Albert Ernest Hammond as I used to be.
I am leaving Sydney 23rd September for Canada, I am tired of everything. I don’t suppose I shall ever see England any more.
Love to all at home, kiss the children for me. Write to GPO Ontario, Canada.
If I have no good luck you will hear from me. I feel very depressed, tired of the War and all its surroundings."
So many people have read that rather desperate final letter, and they all seem to draw different conclusions from it! I have compiled a log of every ship he joined, and every letter he wrote (which reflect many changes in mood). He had mentioned the States before, and even completed an official "Declaration of Intention to become a citizen" but never followed this up with a final Oath of Allegiance which normally follows after two or three years - another example of his constant indecision. (I did find one of these for an Albert Hammond but the timing and signature were wrong). All ideas are welcome, as I reckon he may have gone anywhere or nowhere, and it really does seem to be the ultimate brick wall!
Thanks again for your help,
Alec.
