I don't have a particular interest in this family, I "work the forum boards" so to speak. I am fortunate enough to own the BDM collection of CD's, so if I can share that information with others, I like to do so.
Yes, I retrieved the NZ births from the IGI, and it would not be the first time they are "wrong". I have heard from other researches that they are sometimes quite unreliable, which is a shame, as it is an excellent genealogical site. How "wrong" are they ? Were the children born in NZ ? I guess it depends on whether they were submitted from records or from someone's family tree compilation.
When you say you still need George Bull's death record, does that mean the one for 1923 is incorrect also ? (Or did you mean birth record ?)
I would be happy to supply you with any records from the BDM CD's (VIC, NSW, WA, SA, QLD, TAS) which you might need, and that I can find - just let me know.
