Hi purplemorpheus
... thanks for the clarification.
Obviously we can't rely on information on a death certificate to always be strictly correct, and possibly brother John GUERIN may have confused Ann's length of time in Australia with that of their sister Bridget (arr. 1849) ??
I wouldn't dispute that Annie spent a brief time in New Zealand, but my feeling is, that this was more likely to have been in the period between her arrival in Australia , February 1852, and her marriage in 1854.
My reasoning for this is that New Zealand's immigration schemes for bringing young single Irish girls to this country, didn't commence until many years after 1851. There exists the possibility that she may have come to NZ, say, as a servant of an immigrant family, BUT ... in order to have been a selected emigrant under the NSW scheme, she'd have to have returned to Ireland at some point before 1851-52.
I note her immigration details (to NSW - 1852) record that she was a "child's maid". Maybe once she'd secured work in Australia, she travelled to NZ in that capacity with a family she was employed by ? Unfortunately, NZ (trans-Tasman) passenger records for this early time frame are sparse ... and those that exist tend only to record "employees" of emigrant families, simply as "servant".
I wasn't able to find any suitable record for GEERAN/GEERIN/GUERIN (or for her married name of ALLEN) in NZ records or newspapers.
