The first William died as an infant, yes there are two unnamed births 1879 and 1882; both recorded as male. The 1882 birth was actually a girl named Cora and by other records that provide that conclusion, the previous thread was 9 years ago and I was hoping a fresh look may have found some new information
In looking over several of the 70-odd trees (@ ancestry) for this Sydney & Helen MARSHALL family, there are some inconsistencies, (to be expected), in information.
Hi, I was hoping for some help locating possible information on William Marshall who was born in Campbelltown Tasmania 23 March 1879, family stories tell that he moved to New Zealand.
Cheers

I can see your tree at that site, and the child Cora Blanch(e) MARSHALL is attributed the (27 January) 1882 birthdate.
* What are the "other conclusions" you mention that confirm that birthdate ?
And it's odd that the father Sydney should have registered the birth of an
unnamed male child (rather than a female child) one month after it's birth on 28 February 1882. Or did the registrar make an error about the sex of the child ??
It's also odd that in other trees (@ancestry and elsewhere), that Cora Blanche BARWICK (nee MARSHALL) is shown as having died at Hobart, in 1957, aged 78 years (bc 1879)

* Is her age at death actually confirmed in some other record ??
* What information do you have that Cora was born 1882 rather than 1879 ?
* I'm not terribly familiar with TAS death certificates, but do the certs after 1914, show the number of children of a deceased person ?
Helen M. MARSHALL (the mother) is said to have died in 1922, do you (or fellow MARSHALL researchers) have her death certificate - or a funeral/death notice, which names her children ??
* From the "family stories" you talk about, what evidence do you have that William lived to an age where he might have taken himself off to live in New Zealand ??There are many "William MARSHALL's" who have lived in NZ though may not have actually died here (thereby leaving possibly some record). It's "needle in haystack" stuff searching if we don't have additional information from you.
