My Genealogist, Shiela Pike in Cape Town, found all that I relate here about Caterina and her relationship with the MacLachlans or McLaglens as the Dutch clerks wrote them at times, in Cape Town South Africa.
Philip McLACHLAN of Glasgow, Scotland and Anna Magdelena Adriana Semler, born Cape of Good Hope married 13th August 1824 (A1939 1/2/1)

Cape Town: 4TH March 1821 James Philip, illegitimate son of Philip McLachlan and Catherina Petronella Neyhoff born 15th Jan 1820. Sponsors: Alexander Anderson, Hendrik Neyhoff, Rachel Ovenhyzen,

As far as Mrs Pike could find out these McLachlans came from Scotland in 1819 (after terrible crop failures in Ireland Scotland and parts of Europe caused by the Volcanic eruption called Tambora,in 1816 aftter which it was dark for months on end;no wonder people wanted to emigrate.)

Another Catharina Neyhoff went to China,with James MacLachlan from Cape Town."Surely C P Neyhoff is a relative of your Catherina.
Jacobus Petrus McLAGLEN b.Cape Town 1819. Died insane,Robben Island 16 Sept 1856 aged only 37 years. Father James McLaglen(or MacLachlan as he is officially written in some documents) AND MOTHER:Catharina Neyhoff. He was a printer & he probably ingested lead through the printing ink during work, over a long period.He married Grietze or Margarita, or Margaret, or Gerita RUTGERS grand daughter of Krijn RUTGERS a sea captain whose diary was left in the Africaans Library in Cape Town where it was found by Mrs Pike who got it microfiched and sent to me. I got it translated into English. There is a street named after Rutgers in Cape Town.

Later Mrs Pike wrote: I looked for Neyhoof in the Villiers Pama book but it was not mentioned.Then: Christina Catharina Neyhoff, widow of Francis Lamoer de Manielle 8901/47 19/293 5623/42-3 Christoffel Hendrick Neyhoff, no estate numbers.
Jacobus Petrus McLaglen died 1856 Robben Island. Grietje was his widow , had a small shop behind Cape Town Castle but could not make ends meet enough to support her children, plus keep her husband on Robben Island while he was still alive; so applied for an allowance for him.

Catharina Neyhoff born c.1798.
I found a nEY HOFF IN nEW yORK THIS CENTURY AND THAT IS THE LAST ONE I FOUND.
AT ANY RATE THE Catharina Petronella Neyhoff of Cape Town in the early 1800s IS MY DIRECT FEMALE ANCESTER, MY GREAT GREAT GRANDMOTHER.
