Hi Stuartone
Was William Born 1885 Hobart. Do you have any idea where they may have lived in NZ.
I have found nothing on Archway Archives for them, Nothing significant on the NZSG index, although there is an entry for a William Longman: Pandora box entry. Source: Index to Wills, Lands and Deed Office Wellington by June Springer 1987... This maybe too late for your William though. There is a death for a Catherine Angus 6 Sept 1930 in Omaru but not Longman.
Nothing for them on NZ Histirical BMD's ..Did they have middle names at all?
