Hi, it looks as though someone already has the answer to where Kurilpa is, but I found it when I did a search of Australian voter lists and came up with William and Nellie living in the electorate of Kurilpa district, Griffith sub-district in Queensland in 1963 and before-hand. I had guessed from looking on an online map this was part of Brisbane. Nellie was born on 2 November 1889, I presume this was in Invercargill, New Zealand, where her parents Charles Roff and Jessie Roff nee Taylor lived at the time. I don't know where or when William was born. He first appears in electoral rolls in New Zealand in Wellington in 1919. I can't see that he served in the armed forces in NZ in WWI. Nellie also appeared in a 1919 Wellington roll, previously she had been in the South Island of New Zealand, so they might have been married in Wellington, but of course they might have followed tradition and married where Nellie's parents were living: Invercargill. I have only just found this couple so don't know too much about them including their denomination.
Craig.
