Martha,
David Olphert was "Liverpool City Missionary"; married Agnes Whaley in 1857.
Left Liverpool Nov.1859 - arriving Auckland NZ 16 Mch 1960.
Was accompanied by Robert (Olphert) whom I suspect was a child (not brother) by a marriage to Isabella (surname unknown, dates ditto), presumed died and David remarried (Agnes).
I am seeking info on David's parents; Isabella's ditto...; any brothers or sisters of David...) Kind regards, Derek Olphert.
