Hi Mel
As this is some way from my direct lineage I haven't delved in this area for five or six years.
I would imagine you have a lot more on it than me but this is what I have.
Samuel Cress, baker, born Bradford-on-Avon 26/12/1826 baptised 11/2/1827 at Wesleyan Methodist Church.
Louisa Elvidge Carter born c1834 died 12/4/1906 Tararua NZ. Married 1854 Presbyterian Scots Church, Pitt St., Sydney. District QC Reg V1854954. Took ship 'Shamrock' to Wellington in 1855 (aged 21).
Buried Plot 5378 Old Gorge Cemetery, Tararua NZ, aged 72.
The only children I have are Charles Samuel Cress, Labourer 28/4/1856 Wainuiomata, Wellington NZ, Louisa Cress 30/11/1857 Wainuiomata, Wellington NZ, John Henry Cress 7/7/1862 Ferry Road, Christchurch, NZ. He married Amelia Gibson on 2/1/1886 at Presb Church Kaikoura, and died 13/11/1937.
If you would care to look at my tree on Genes Reunited you may find out more. Hope it's of some help.
Best Regards
Jim
