I am getting a little lost with it all so will need a few days next week to process it all of which will be a real joy...
Thanks once again

Hi Rob,
I agree it is confusing and tangled.
Put simply, the way I see it anyway, is that Thomas Elder BOYD is the man with whom Julia CURTIS had a relationship and children.
There was not a marriage.
To conform with the expectations of society at the time, she just twisted his name round a bit and added in CURTIS to make the children seem legitimate upon registration of their births etc. She continued to call herself Julia CURTIS and he continued known as Thomas Elder BOYD, but at times used CURTIS.
It seems the relationship endured at least "off and on" as he was a witness on the marriage of a daughter Julia Laura. {see signatures}.
When he died in 1906, his death notice says he died in Brighton-the suburb noted in many CURTIS/MOORE events- But unfortunately no specific address is given in 1906 for Thomas Elder BOYD's death place.
It may well be on his death certificate as well as other family information to confirm or otherwise this connection.
My version of things anyway

ADDING
As a footnote here.
Looking back through my notes here I did find , but did not post, that Thomas Elder BOYD was a property owner of a few places around South Yarra and Prahran in 1860's and 70's.
and remembering Judith found property in the name Thomas CURTIS, it seems he was using both names BOYD and CURTIS at that time.
