I am trying to track down the descendants of John Morrison Pottinger (b.1823 Lerwick, m.1858 Islington, Janet Mutter) . At least one of his sons has a NZ connection:-
Arthur William Pottinger (b.1866 Islington) married 22 Oct 1888 Fanny Gertrude Morton at Christchurch.
Their daughter
Marjorie [Morrison] Pottinger (b.1890 New Zealand m.1910 Charles Douglas Simmons)
I have also found mention of a Robert J Pottinger who married Mary Gifford Laurenson (born 6 May 1865) at Christchurch, NZ, 6 Jun 1889.
If this ties in with anyone's family tree or if you have any information I would be delighted to hear from you. I have a brief family tree at:
