Hello Lyn...
Welcome to Rootschat

I'll assume you're starting from scratch so...
An Elizabeth Ann GEORGE married a Robert JEFFERY in 1879. They had three children that I could find, namely...
Hannah Blight JEFFERY b.1879
Edward Blight JEFFERY b.1880 and
Eliza Blight JEFFERY b.1882
The middle name of the children makes me think this Robert JEFFERY is your Robert
but I've no proof of that.
The marriage and births can be found on the BDM NZ website.
https://www.bdmhistoricalrecords.dia.govt.nzI note a Hannah Blight JEFFERY, daughter of Robert Blight JEFFERY, married a Charles YOUNG and is mentioned on the Australian Marriage Index. This index can be found on ancestry.com
An Eliza Blight JEFFERY marrying a Wm SCOTT is also mentioned in the same index. It possibly corresponds to the following record...
Auckland Born NZ'ers who married in Victoria, Australiahttp://freepages.genealogy.rootsweb.ancestry.com/~babznz/straysvic20.html-----
A Hannah Blight YOUNG d.1955 is mentioned in the Australian Deaths Index, also on ancestry.com
Possibly corresponds to the following record...hope the link works
Adelaide Cemetery Authorityhttp://www.rootschat.com/links/0u0v/---
LDS has a possible arrival. A Robert JEFFERY from Cornwall arrived in NZ in 1874 aboard the Geraldine Paget". Aged 24 so born c.1850. Accompanied by a Harriet JEFFERY, aged 20.
Hope the link works...
