Ros, thanks, I have found two Asgill-Tucker addresses in Australia, but when I wrote, both said they were no longer at that address. Thanks for this one, I'll give it a try.
Debra, his death certificate (1939) says "How long in Australasian colonies or states?" as "40 years in NSW", which would make him arriving from overseas around 1899. But was this true? I can find no immigration record for then, or any other time, and I know he must have been in Victoria long enough to meet and marry my grandmother - though that may have been a short time because she was in an unhappy family situation, and may have married to get away (my mum said they more or less eloped).
If he spent a long time in NSW, it would scuttle the idea he copied his name from Francis and Mary, who were always in Victoria after they arrived from Ireland.
I would love to find a reference to him in NSW pre 1913, and there are a few possible references in the Sands directories, but nothing conclusive.
Judith,
I think that is the correct marriage for the couple of interest, and may well be the right shipping link (as an Irish person, he could have travelled via Liverpool). But as you say, they don't seem to get us any further.
Thanks again to all of you.
