cert. reads: 1882 in the District of New Plymouth on Feb 4, Matthias Rowe, 28, laborer (sic) bachelor born Plymouth, England, s/o William Rowe, farmer and Honor Daw married Caroline Emma Austin Gibson, 26 (really 28), spinster, b. Melbourne, Victoria, d/o William Austin Gibson, laborer, and Emma Clinton. Both resident New Plymouth and signed their names. Wit: Ellen Maria Martin and N Martin Turner (Turner may possibly be occupation not surname. Not known to be any relation or connection)
NB this turns out to be an interesting mix of fact and fiction, as Emma's father was really William Austin and her step-father John Gibson.
It may be possible to confirm family relationships with Matthias by comparing test results with other carriers of his Y-chromosome or his mother's mitochondrial DNA.
