I am not connected in any way, but in looking at your problem, I presume that Kaiee lived on Norfolk Island, and married? there. All the Anglican marriage and bith records, plus banns and burials,for Norfolk Island, are available as PAMBU microfilms. So are the 7th Day Adventist records
PMB 423-C of E records 1871-1971
PMB 425 7th Day Adventist records 1891-1970
THere are also other films from the Norfolk Island Historical Society.
I suggest you get in touch with PAMBU to ask where the nearest library to you which holds these films firstname.lastname@example.org
