emvee on Family Tree Circles

I found some information posted several years ago. I am a descendant of this family. they were my great great grandparents. Their daughter Anna Maria Marshall b.19.7.1869 - d 31.3.1938 married Frederick Westbury b 3.5. 1862 - d 14. 4.1943. they lived in Johnsonville, then moved to Lower Hutt New Zealand.
The only information I have of the Marshall's is that they landed in Nelson in 1842. After a few years residence in the Nelson district they left to try their luck at the Bendigo diggings in Australia, but after a short while returned to New Zealand and settled at Johnsonville where Anna Maria was born, being the youngest of a family of fifteen, who are listed in the 2008 listing of this site.
I only have names and married surnames for Elizabeth Jane ( O'Loughlin) Emma,(J. Hobbs /G. Crowe) John Isaac, Sarah,(Martin) Alice, (Pat Crowe)William, Thomas Edward, Frederick, Alfred, Anna Maria, Frederick Westbury) Mary (J. Gray/Swan)
I would appreciate any further information.
