Am trying to get hold of my friend and get him to have another look and try to see if he can jog some of the family to see if any of this rings bells .

What I should have said that Ellen LUND is his great grand mother & Eda is his grandmother.
Had a look at BDM for the children named:
Elizabeth Ann FONG b 1886
GEORGE FONG b 1883 sold to a chinaman ??
Lily

b

,
There is a Lily Fong on BDM with different parents born after 1901
Also a Lily Chow FONG married 1919 Yip BOR, not sure if same as above.
Eva Ellen LUND maybe Eda Ellen Lund b 1889.
Wonder if Ellen Elizabeth DOUGLAS married in the UK and came to NZ with ? SHEFFIELD, took up with Ah FONG (children) and then married John LUND. At present it could fit in with the dates.
A mystery lady with many names.
