The Jouberts and Duminys of the winelands
The one line that never lived in the Karoo, and reached it three times anyway - in 1904, 1945 and 1946, every time through a woman. It also holds the only one of the four origins this record can put on a map: a foundling born at Lorient in Brittany in 1747, who became a Dutch East India Company sea captain, harbour master at Simonstown, and a slaver.
Three of Frans's four grandparents come out of families that walked into dry country and stayed there. This is the fourth, and it is the odd one: a line that never lived in the Karoo at all.
Four generations of Jouberts stay inside a circle about forty kilometres across, between Kuils River, Durbanville and Stellenbosch, while the Oosthuizens were crossing the colony eastward and the van der Merwes were going north-west into the Hantam. They were town and wineland people. Nobody in this story holds a Karoo farm.
And yet the family reaches the Prince Albert district three times in forty years, every time through a woman. That is what this page is actually about.
It also holds the only one of the four origins that can be named here with a place, a date and a document behind it. The others begin in an argument about a Dutch or German town, or in a compiled tree with no origin at all. This one begins in Brittany, and the record says which street.
Two lines that join in 1910
The Jouberts, in the male line:
| Born | Died | |
|---|---|---|
| Johannes Jacobus Joubert | 17 July 1809 | 17 March 1888 |
| his son Dirk Daniel | Kuils River, 19 June 1843 | Stellenbosch, 2 February 1914 |
| his son Christiaan Wilhelm Johannes | 11 June 1881 | 26 August 1962 |
| his daughter Anna Tobia Jeanne | 27 July 1915 | 11 November 1974 |
The Duminys, who marry into them at the last step but one:
| Born | Died | |
|---|---|---|
| Antoine Lebre Duminy | 2 July 1691 | 22 February 1768 |
| his son François Renier, the one who came | Lorient, 4 October 1747 | Cape Town, 26 May 1811 |
| his son Benjamin Jacob Wilhelm | 10 June 1793 | 5 November 1862 |
| his son Francois Jean van Helslandt | 22 August 1818 | 28 December 1908 |
| his son Francois Jean van Helslandt | 12 September 1853 | Blaauwberg, 27 June 1937 |
| his daughter Francoise Jeanne | 12 May 1882 | 14 October 1975 |
Francoise Jeanne Duminy married Christiaan Wilhelm Johannes Joubert at Durbanville on 16 April 1910, six weeks before the four colonies became one country. Their daughter is the grandmother this line reaches Frans through.
A foundling from Lorient
François Renier Duminy was born a foundling at Lorient in Brittany on 4 October 1747. Lorient was the home port of the Compagnie française des Indes orientales, and he went to sea in its service.
He then changed companies and countries. He came into the service of the Dutch East India Company as a sea captain, reached the Cape in 1771, and married Johanna Margaretha Nöthling at Cape Town on 2 February 1777. He was Equipage Master for the Company in 1786 and 1787, and Captain of the Port at Simonstown from 1803 to 1806.
Those last three years are worth a sentence of their own. He held that post under the Batavian administration, and it ended in the year Britain took the Cape for the second time. A harbour master appointed by one government does not usually survive the arrival of another one's fleet. He was also a cartographer, a farmer, a public commissioner, and a decorated freemason at Lorient and at the Cape. He died at 19 Graave Street, Cape Town, aged sixty-three.
He was also a slaver, and that is set down plainly because it is true. He is not the only part of the record that has to be stated rather than arranged. Two of the enslaved and free black women who stand as founding mothers of this whole ancestry belong in this line and not in the other three: Marij van Angola, through Maria Johanna Emerentia van Oosterzee, and Souwa van Madagascar, through the Zeederbergs. So the same four generations of one wineland family hold a man who trafficked in people and the descendants of women who were trafficked. Both are ancestors. Neither cancels the other, and they do not resolve.
A third woman, Maria van Bengale, has been claimed in this ancestry and the claim is disproven. What joined her to this family was a surname and nothing else.
Four generations that do not move
Johannes Jacobus Joubert was born on 17 July 1809 and married Christina Wilhelmina de Jongh on 24 December 1833.
His son Dirk Daniel Joubert was born at Kuils River on 19 June 1843, married Anna Tobia Jeanne Neethling at Durbanville on 1 October 1866, had eleven children by her, married again after her death in 1890, and died at Stellenbosch on 2 February 1914. Kuils River to Stellenbosch is about twenty kilometres. In the same seventy years the Oosthuizens had gone from the Olifants River to the Koup and the van der Merwes from Piketberg to Calvinia.
His son Christiaan Wilhelm Johannes Joubert was born on 11 June 1881 and married at Durbanville in 1910, in the same village his father had married in forty-four years earlier.
This is the thinnest of the four lines. No farm, no death notice, no register page has yet been read for any of them. What is held is names, dates and marriages, out of a compiled tree and a family genealogy. not yet verified That is a gap in the research and not a statement about the family.
The name that keeps coming back
Anna Tobia Jeanne Joubert was born on 27 July 1915 and carries her grandmother's name exactly: Anna Tobia Jeanne Neethling, 1841 to 1890, who died twenty-five years before this child was born.
Note the trap in that name. There is a second Anna Tobia Jeanne Neethling in the wider tree, born 1831 and dead 1909, of Neethlingshof. They are not the same woman and they are not joined here. not yet verified
The Duminy name does the same thing, sideways. It stops being a surname and becomes a given name in the next generation: Anna Tobia Jeanne's sister was christened Frances Duminy Joubert. That is how you can see, from a first name alone, which marriage a person came out of.
Three women, and the road to Prince Albert
Now the part that puts a wineland family into a Karoo record.
1904. Maria Johanna van Oosterzee Duminy, Francoise Jeanne's elder sister, married Jacobus Daniel Abraham Oosthuizen on 19 September 1904. He was a farmer at Zeekoegat, in the Prince Albert district, and his family built and filled the church out there. She died at Prince Albert on 7 April 1916, aged thirty-six.
1945. Frances Duminy Joubert, Anna Tobia Jeanne's younger sister, married Gert Annis "Tokkie" Marincowitz at Bellville on 25 August 1945. He farmed Rondabel and ran the Prince Albert Landbougenootskap. She died in 1965.
1946. Anna Tobia Jeanne Joubert married Hendrik Lodewyk Malherbe Oosthuizen at Bellville on 25 May 1946, nine months after her sister and in the same town.
So in forty-two years this one wineland family sent an aunt, a sister and a daughter into the same small district, into three of the families whose ground this history follows. None of them married a neighbour. All three marriages were made at the Cape end and the women moved.
Anna Tobia Jeanne died on 11 November 1974 and is buried in the Prince Albert church cemetery, beside her husband. Her mother, Francoise Jeanne Duminy, outlived her by eleven months and died in 1975, at ninety-three.
What this line is, in one line
The other three families are known through ground: diagrams, quitrent titles, deduction tables, farms held for a century. There is none of that here, and there may never be, because these people did not hold Karoo ground.
They are known instead through marriages, and the marriages are the point. A history that followed only the men holding title would not contain this family at all, and would then be unable to explain where a Prince Albert farmer's wife came from in 1904, in 1945 and in 1946. Three times the line that never came to the Karoo is the reason somebody else did.

Research notes
[11 Aug 2026] Written when S036 was split into one story per ancestry line. THE THINNEST OF THE FOUR: no farm, no death notice, no register page has been read for any Joubert here, and the page says so rather than padding. Francois Renier Duminy's slaving and the two Cape matriarchs who stand in the SAME line are both stated plainly, per 10. The Maria van BengaleM descent is disproven and is pointed at STO-0021 rather than repeated.
[12 Aug 2026] VOICE REWRITE to STORY-VOICE.md, both languages. en 1/5/0 -> 0/0/0, af 5/5/0 -> 0/0/0 (narration/bold-sentence/punchline). Ten bolded sentences removed. This is the last of the four grandparent-line stories to be passed; S035 is the benchmark and S037 and S038 were done earlier today. || ONE ARITHMETIC ERROR CORRECTED AGAINST THE RECORD. The page said Francois Renier Duminy 'died at 19 Graave Street, Cape Town, aged sixty-four'. PER-000072 gives his birth as 4 October 1747 and his death as 26 May 1811, so he had not reached that year's birthday and was SIXTY-THREE. Corrected in both languages. Same class as the S032 age, and treated the same way: arithmetic against a linked record is not a research question. Note the page cites no source for the age, so if a death notice states sixty-four the correction should be revisited and the disagreement recorded instead. || THE SAME FRAMING FAULT AS S037, and it is worth naming as a pattern: 'into three of the families this site is built on' ranks families by the site's own attention, which 1 exists to prevent. It now reads 'into three of the families whose ground this history follows', which is what the evidence actually supports. Also removed 'the only one of the four origins this record can name', 'this is the thinnest of the four lines IN THIS RECORD', 'this project already held him', 'this record does not join them', 'the other three families IN THIS RECORD are known through ground', and 'A Karoo record that followed only the men holding title'. || THE SLAVER PASSAGE IS UNTOUCHED IN SUBSTANCE. 10 requires this material be handled with accuracy and respect and neither euphemised nor sensationalised, and the passage already does that: Francois Renier Duminy trafficked in people, two of the enslaved and free-black founding mothers descend into this same line, both are ancestors, neither cancels the other. Only 'the page does not pretend they resolve' was recast to 'they do not resolve', because the claim is about the history and not about the page. || CHECKED AND CORRECT: every other date in both tables, and the derived figures - Maria Johanna thirty-six at her death in 1916, Francoise Jeanne ninety-three in 1975 and outliving her daughter by eleven months, Anna Tobia Jeanne NeethlingM dead twenty-five years before her namesake was born, forty-four years between the two Durbanville marriages, forty-two years across the three Karoo marriages, nine months between the sisters' weddings. The three enslaved-ancestor links also agree with S021 and S030 on which line each enters through. verify_af passing.
