I have since determined that Henrietta Dryden nee Brink is the daughter of Daniel Frederick Berrange Brink and Henrietta Christina (maiden name unknown).
I believe that Daniel Frederick Berrange Brink is the son of Francois Gerhard Jacob Brink and Maria Magdalena Berrange, but I don't have any hard evidence for this aside from the family tree compiled on Pelteret.co.za and a FamilySearch.org record.
Daniel and Henrietta had eight children, four of whom died before their mother did; Henrietta died 6 July 1940, in Cape Town:
- Henrietta Dryden nee Brink, died March 1943, Cape Town - Martha Brink - Henry Brink - John Daniel Brink, possibly born 17 July 1865, Died 28 Jan 1916, married to Martha Susan Maria Sinden, one daughter named Kitty - Frederica Marie Magdalena Perich nee Brink, born c.1871, died 23 Sept. 1945, married to Nicholas Perich, at least one son, Nicholas Gregory Perich - Minnie Brink - James Brink - Daniel Frederick Berrange Brink jnr., possibly married to Wilhelmina Frances (maiden name unknown).
Any additional information on any of this individuals is welcome, Craig
