I have a few ancestors which are a mission to research back into Ireland but also create a little confusion once they arrived in NZ. As best I can tell they came here perhaps in steerage class in 1862 or there about. From a marriage record in 1869 I can see the couple, Hugh Hall and Jane Tosh tie the knot. Later, they raised a family at Thornbury. Their marriage certificate indicates the witnesses were an Elizabeth Tosh and a John Hall, a relative of each of the couple, then the two witnesses appear to themselves tie the knot in 1871. Suggests a concentration of Halls and Toshs in Invercargill and Riverton area in that period. Any thoughts or suggestions for digging deeper?
