Hi Phil,
There's passenger arrival into Brisbane (Qld) 11 Apr 1923 from Naples of Guiseppe Sante Maria (Sante !) aged 36, on Osterley. His nationality "British" .... (could be British subject, ie born in Britain and/or in any of her dominions, including Australia, coming to OR returning to Australia!)
NSW ER 1943
201 Hargraves St Paddington : Santa Maria surname:
Guiseppe, Male, fruiterer
Gaetano, Male, no occupation (frequently that seems to indicate an Old Age Pensioner)
Josie, saleswoman
Mary, home duties.
Do you think your Joseph may have been a member of that family?
PS, being on the roll in 1954 doesn't mean she was living, it just means that the family may have not notified the Electoral office, most families don't notify the electoral office even today!
Cheers, JM
