Research notes

[SRC-073 + tree] FATHER OF THE ROOT ANCESTOR PER-000001, and so one generation further back than the model went before. Married Susanna Catharina van TonderHen 26 Jan 1783 in the Overberg. Pottas gives his birth as 1754, the tree as 1755. Died about April 1809 on de Modder Fonteyn - i.e. the family was still away from the Karoo a generation before Beaufort West.

29 Jul 2026 FamilySearch: married Susanna Catharina van TonderHen 26 Jan 1783 at SWELLENDAM (the tree said Overberg). FS id CORRECTED 29 Jul 2026 to LHLG-S2Z; it was first recorded as "LHIG-S27" off a small render - an I for an L and a 7 for a Z. Thirteen children.

29 Jul 2026 [SRC-077]: the death notice of his son names him "Okker Almero Oosthuijsen", and the 1786 baptism register gives him simply as "Ocert Oosthuijsen".

*** [14 Aug 2026, CORRECTED - THIS ROW READ THE 1859 NOTICE THE WRONG WAY ROUND FOR SIXTEEN DAYS.] *** The sentence above used to end "so the father carried Almero too", and S008's whole argument is that he did not: he was baptised plain OCKER in 1755, and a death notice written by his son's family in 1859 - fifty years after he died - is the one document that gives him Almero. That is a courtesy written backwards onto a dead man, not a name he carried, and it is exactly the kind of back-formation this project is supposed to catch. S008 was corrected on 13 Aug 2026 and this row was not, so the site argued both readings at once until HIS display_name has lost the parenthetical Almero for the same reason.

29 Jul 2026 [SRC-086, SRC-087] *** WHERE HE LIVED IS NOT ESTABLISHED, AND THIS PASSAGE USED TO SAY IT WAS. *** It read "CITRUSDAL CONFIRMED FROM TWO DIRECTIONS" and was written that way for three weeks. WHAT THE TWO DIRECTIONS ACTUALLY ARE: family memory has it that the first Almero or his parents lived at Citrusdal and Frans has been to a property there that still stands; and the family-tree independently gives his death place as Citrusdal. Two sources that have never met, agreeing on a place field 5 says to distrust - which is suggestive and is not proof. WHAT OVERTURNS IT: the 1809 estate was taken before A.A. FAURE, LANDDROST OF SWELLENDAM (SRC-465), and a landdrost's authority was territorial. Citrusdal was Tulbagh and from 1808 Clanwilliam. See LEAD-0220.

THE 1786 BAPTISM CONCLUSION SURVIVES THE WITHDRAWAL, and it is worth saying why rather than losing it with the premise: there was no congregation in the Olifants River valley until Clanwilliam in 1826 - until then it "formed part of the town Tulbagh", with a predikant riding out annually to baptise. So a family at Citrusdal in 1786 belonged to TULBAGH (ROODEZAND). The same answer arrives from the other side too: Swellendam, where he married in 1783, had no congregation of its own until 1798, so its people also went to Tulbagh or Cape Town. Both hypotheses converge on Tulbagh - which is where his own parents married in 1749.

29 Jul 2026 [SRC-091] BAPTISM REGISTER READ, 1755: "t kint OCKER, vader Jacobus Oosthuijsen, moeder Diena Carola Brits, getuigen OCKER BRITS en Johanna BothaM." HE WAS BAPTISED SIMPLY OCKER - NO ALMERO. The second son takes the mother's father's name, and Ocker BritsM is standing at the font. The Almero only arrives with his own son in 1786. His son's 1859 death notice calls him "Okker Almero", which is a later back-formation, not what the register says.

[SRC-092] MOOC8/28.63, 23 April 1809: he died INTESTATE at DE MODDER FONTEYN on the OLIFANTS RIVER (PAR-000065). WHICH Olifants, and which Modder Fonteyn, is open - that clause used to read "the Citrusdal place, now documented". Eleven heirs named with their ages. The inventory speaks of "het afsterven van zijne ouders" in the plural, so SUSANNA CATHARINA VAN TONDER HAD ALSO DIED BY APRIL 1809.

*** [4 Aug 2026, SRC-092 / INV-0005] HY WAS 'N SMID, EN DIE WERF HET DIT NOOIT GESÊ NIE. *** His 1809 inventory, taken at de Modder Fonteyn on the Olifants River, lists a complete forge among the household goods: EEN OUDE BLAASBALK (bellows), een ballast yzer, TWEE VOORHAMERS, een handhamer, een tang, een schroef, and an yzere balans met kopere schaalen. The clerk's own room-by-room walk names the room they stood in - voorhuis, the two side rooms, the combuis, and THE WINKEL. Winkel here is the smithy, not a shop. AND HE WORKED WOOD AS WELL AS IRON: twaalf stukken hout, vier geelhoute planken, EENIGE STUKKEN WAGEMAKERSHOUT - wagonmaker's timber - beside an ox-wagon and 'een chais, DEFECT'. A broken chaise in a house with a forge and wagon timber is a job in progress, not a possession. WHY IT MATTERS BEYOND THE MAN. This project has described the generation before the Karoo as trekboers moving east. A forge is the opposite of that: it is fixed capital, it needs charcoal and a water supply, and it makes its owner the man a whole district depends on for a wagon tyre, a share, a hinge. It also travels well as a SKILL - the family that took up ground in the Koup a generation later carried a trade with it, not only stock. WHAT IS NOT CLAIMED: no document calls him a smith. The occupation is read off the tools, the wood and the name of the room, which is inference and is marked as such. The estate was wound up ab intestato and the farm sold to his eldest son Jacobus Johannes for 1 000 rixdollars, so no will states a trade either. [TO VERIFY] - the opgaafrol would give an occupation directly, and LEAD-0078/0079 are already open on which roll to read.

[17 Aug 2026] "ALMERO" TAKEN OUT OF HIS GIVEN NAME, and it was load-bearing. This row read "Ockert Almero" in `given` while S008 and SRC-076 both say the opposite: the 1786 baptism of his son names the father plain OCERT OOSTHUIJSEN, and only the son's 1859 death notice writes the old man back as "Okker Almero" - a courtesy the register does not carry.

THE FIRST ALMERO IS HIS SON, PER-000001, baptised Occert Almaro on 11 May 1786.

WHAT RESTED ON IT: the whole identification of the 1833 Vrolykheid grantee. "As. son" was read as "Almero's son" and pointed at this man's son PER-000208, which only works if this man was an Almero. He was not, so it does not. See PER-000043 and LEAD-0213.

[17 Aug 2026, SRC-451] HIS NAME WAS OCKERT JACOBUS, and THREE INDEPENDENT LINES NOW SAY SO. (1) The 1867 death notice of his eldest son names the parents "Ockert Jacobus OosthuizenL & Susanna Catharina van TonderH". (2) That son's own first son, born 1809, is OCKERT JACOBUS (PER-000211). (3) His second son's first son, born 12 July 1813, is ALSO Ockert Jacobus (PER-000124). The vernoemingspatroon gives a first son his father's father, and two brothers independently produced the same name four years apart.

SO HE WAS NOT AN ALMERO, and this is now a documented finding rather than an inference. His own 1809 estate (MOOC8/28.63) styles him "Ockert Oosthuijzen" while his son signs "Ocker Almero Oosthuysen" on the same sheet - the Almero enters with the SON. Every tree that calls this man "Ockert Almaro", including the AS Oosthuizen descendancy export, is reading the name backwards down the generations.

The forms are all kept, per 5a note 6: "Ockert Jacobus" (1867 notice), "Ockert Oosthuijzen" (1809 inventory), doopnaam "Ocker".

[17 Aug 2026, SRC-455 - AND IT CHANGES WHAT THE NAME IS, not only what it says]. The baptism of his son Jacobus Johannes records the father as "OCKER OOSTHUIJSEN", plain, with the witnesses being JACOBUS OOSTHUIJSEN AND DINA CAROLINA BRITZ - his own parents. So the "Jacobus" that the 1867 death notice attaches to his name is very likely a PATRONYMIC and not a second given name: Ocker, Jacobus's son. Every official record of him reads "Ocker" or "Ockert" alone; the Jacobus appears when somebody needed to say WHICH Ocker. Recorded as Frans's reading ofand adopted, because it explains all three forms at once rather than picking one.

[18 Aug 2026, CONSISTENCY RUN] The Citrusdal identification is no longer carried as fact. The 1809 estate was taken before A.A. FAURE, LANDDROST OF SWELLENDAM (SRC-465), whose authority was territorial and did not reach Tulbagh or Clanwilliam, where Citrusdal lay. See LEAD-0220.

*** [20 Aug 2026, SRC-514] THE OLIFANTS IS THE SOUTHERN ONE. *** The Swellendam baptism of his youngest son records this household 'woonende aan Oliphants Rivier' and bringing the child to Swellendam. Citrusdal was Roodezand's congregation and then Clanwilliam's, 400 km the other side of the Cape; the Little Karoo Olifants was Swellendam district until George was cut off in 1811. That agrees with A.A. Faure taking his estate as Landdrost of Swellendam in April 1809 (SRC-092), with the 1808 Swellendam roll, and with his children appearing on the 1816 GEORGE roll (SRC-459) without the family having moved. THE FARM ITSELF IS STILL UNLOCATED - no Modderfontein survives anywhere along that river in the cadastre (SRC-510) - so the river and the district are settled and the ground is not. LEAD-0220.

[20 Aug 2026, SRC-515] AT GRAAFF-REINET IN SEPTEMBER 1799, twice on one opening: baptising his son Roelof, and standing witness with his wife at the baptism of a Besuijdenhout child. THIS IS NOT A RESIDENCE. The entry carries no 'woonende aan' clause, where the 1808 Swellendam entry does, and the godfather is a van Tonder standing to a van Tonder's namesake - the shape of a visit to the wife's people. Frans made that point the moment he sent the page. So the household's 1808 address on the Olifants is untouched by this.

[20 Aug 2026, SRC-516] AT SWELLENDAM AGAIN. His daughter Sara Maria, born 16 November 1803, is baptised in the Swellendam register G7/4/1 - the volume before the one that records the household 'woonende aan Oliphants Rivier' in 1808. Three baptisms are now placed: Graaff-Reinet in September 1799 (SRC-515), Swellendam about 1804 (SRC-516) and Swellendam in 1808 (SRC-514). The two Swellendam entries bracket the 1807 marriage and neither is a stray.

Superseded: answered below *** [20 Aug 2026, SRC-517] AND ONE BAPTISM IS AT SWARTLAND, WHICH DOES NOT FIT THE OTHERS. *** Susanna Johanna, born 19 March 1801, was baptised at SWARTLAND - Malmesbury, north of Cape Town - on 6 December 1802. The four known baptisms of this household now run Graaff-Reinet 1799, Swartland 1802, Swellendam c.1804, Swellendam 1808. THE OLIFANTS READING IS NOT OVERTURNED: only the 1808 entry states a residence, and the Swellendam landdrost took his estate in 1809. BUT THE BOLAND OLIFANTS IS BACK AS A POSSIBILITY rather than closed, because Swartland sits on the road north to Piketberg, Clanwilliam and Citrusdal. Whether this family moved across the colony or merely travelled far to church is not established here and must not be written as though it were. LEAD-0260.

*** [20 Aug 2026] A COUNT WORTH KEEPING IN VIEW: parentage gives this man EIGHTEEN children and the 1809 inventory names ELEVEN surviving heirs. Some of the difference is children who died before 1809 and some of it is duplication - three doubled pairs are already identified (PER-000141/342, PER-000142/346, PER-000148/352) and two inventory rows duplicate FamilySearch rows (PER-000294/147, PER-000295/149). Nothing that counts this sibship should be trusted until that is cleaned up. LEAD-0259.

Superseded: answered below *** [20 Aug 2026, SRC-518] AND THE EARLIEST OF THE FIVE IS AT ROODEZAND. *** Pieter Marthinus, born 9 June 1795, baptised at Tulbagh on 27 March 1796, with two of the mother's kin standing. The household's known fonts now run ROODEZAND 1796, GRAAFF-REINET 1799, SWARTLAND 1802, SWELLENDAM c.1804, SWELLENDAM 1808. TWO OF THE FIVE ARE WESTERN CONGREGATIONS ON THE ROAD TO THE BOLAND OLIFANTS, which is where the family has always said the Modder Fonteyn was. The 1808 residence clause and the Swellendam landdrost still point the other way. THIS PROJECT DOES NOT KNOW WHICH OLIFANTS, and after today it knows that it does not know, which is better than it was this morning. LEAD-0260.

Superseded: answered below *** [20 Aug 2026, SRC-519] AND A SIXTH FONT, AT PAARL - WHICH CHANGES HOW THE OTHER FIVE SHOULD BE READ. *** Gert Adriaan, born 2 January 1794, was baptised at Paarl in October 1799, a month after this couple stood IN PERSON as witnesses at Graaff-Reinet, 700 km away. Both cannot mean the parents travelled. The godparents at Paarl are his own kin, Gert and Adriaen Oosthuijsen, and the child is named for them: the boy was presented by uncles. SO THESE SIX ENTRIES MAP THE FAMILY'S KIN NETWORK - Roodezand and Graaff-Reinet with van Tonders and van Wijks, Paarl with Oosthuizens - AND NOT THE HOUSEHOLD'S ADDRESS. The western cluster of Roodezand, Paarl and Swartland is therefore weaker evidence for a north-west residence than it appeared, and SRC-514's 'woonende aan Oliphants Rivier' remains the only statement of where these people actually lived. LEAD-0260.

*** [20 Aug 2026] THE DISTRICT IS SETTLED: SWELLENDAM, AND THEREFORE THE SOUTHERN OLIFANTS. *** SRC-497, the 1805 Swellendam opgaafrol J 318, counts this household at entry 784 - 'OCKERT, Susanna Catharina van TonderHen, 1|1|6|4' - with his two eldest sons already householders at 788 and 789. A man is counted in one district. That, with Landdrost Faure of Swellendam taking his estate in 1809 and Secretary Stockenstrom of Swellendam signing in 1802, puts de Modder Fonteyn in the Swellendam district and so on the SOUTHERN Olifants, in the country cut off as George in 1811. The six baptisms scattered across Roodezand, Paarl, Swartland, Graaff-Reinet and Swellendam record where his KIN were, not where he lived. LEAD-0260 closed; LEAD-0220 keeps the farm.

[20 Aug 2026, SRC-520] AND THE OTHER SIDE OF IT: With the 1751 Drakenstein roll also holding none, this family is absent from that district across half a century and present in Swellendam's throughout.

*** [20 Aug 2026, SRC-497] HIS 1805 FARM MAY BE NAMED, AND IT IS MODDERFONTEYN. [TO VERIFY] *** On the 1805 Swellendam roll his household is entry 784, and the facing landerijen leaf carries '1. Modderfonteyn' on what measures as that row. Measured off two screenshots rather than read off the page, so it is marked and not asserted. If it holds, the farm he died on in April 1809 is named four years earlier, under the same name - but among neighbours (Vals Rivier, Berg Rivier, groote Heuvel, Riet Valey, Zeekoegat) that are Swellendam and Riversdale country and not an Olifants, which leaves the 1809 inventory's 'gelegen aan d'Olifants rivier' to be explained rather than confirmed. LEAD-0220.

*** [20 Aug 2026, SRC-497] THE 1805 ROLL NAMES HIS RIVER: 'AAN D' OLYPHANTS RIVIER, 43 UUREN' from the Swellendam drostdy. *** The same river the 1809 estate names, four years earlier and in another hand - so 'gelegen aan d'Olifants rivier' is corroborated rather than isolated. 43 uuren is about 227 km and puts the farm at the far edge of the Swellendam district, which ran east to the Gamtoos until George was cut out in 1811. It eliminates the Riversdale Modderfonteins at 14 uuren. It does NOT eliminate Citrusdal on distance, which is 39 uuren by the same calibration - that is done by the roll being Swellendam's and Citrusdal being Tulbagh's. LEAD-0220.

*** [20 Aug 2026, SRC-522] THE RIVER HE DIED ON IS SETTLED AS THE SOUTHERN OLIFANTS. *** Two years after his death his heir is enrolled in the brand-new GEORGE district with a place 'aan Olyphants Rivier'. George was cut from eastern Swellendam in April 1811; Citrusdal was Tulbagh's in 1805, 1809 and 1811 and never became George. With the 1805 roll's 'Modderfonteyn aan d' Olyphants Rivier' and Faure taking the estate on the farm, every link in the chain is now a document.

*** [20 Aug 2026, SRC-534] AND A TRAVELLER CONFIRMS THE DISTRICT FROM OUTSIDE THE ARCHIVE. *** John Barrow, travelling 1797-98 and printed in London in 1801, refers in passing to 'Zjardt Van der Walt, of OLIFANT'S RIVER IN ZWELLENDAM'. Eight years before the roll that counts this household at Swellendam holding Modderfonteyn 'aan d' Olyphants Rivier', an English visitor with no stake in the question uses the same pairing as ordinary geography.

*** [23 Aug 2026] THE SIBSHIP MARRIED IN BLOCS, AND IT IS THE SHAPE OF THIS WHOLE PROJECT. *** Of the thirteen children of Ockert Jacobus OosthuizenL (PER-000118) with a recorded marriage, SEVEN married children of just TWO households - and in each case they married SIBLINGS.

THE VENTER BLOC, all children of Jan Louis VenterL (PER-000120, b.1754) and Johanna Jacomina SmitM: Ockert Almero x ADRIANA CECILIA VENTER (Oct 1807, Swellendam); Dina Magdalena x JAN LOUIS VENTER the younger; Cornelia Petronella x PETRUS JACOBUS VENTER.

THE STRYDOM BLOC, all children of Daniel Jacobus StrydomM (PER-000337) and Anna Magdalena CalitzM (PER-000338): Jacobus Johannes x ANNA MAGDALENA STRIJDOM (6 Mar 1808, Uitenhage); Cornelis Andries x JOHANNA MACHTELD PETRONELLA STRYDOM (11 Apr 1813); Roelof Adolph x HESTER MARIA CATHARINA STRYDOM; and SARA MARIA OOSTHUIZEN x DAVID JAN STRYDOM - the man granted RONDABEL on 15 April 1841.

A LIKELY THIRD PAIR: Gerrit Adriaan married Petronella Catharina SchoemanM and Pieter Marthinus married Catharina Elisabeth SchoemanM. Neither Schoeman has a recorded parent here, so whether they were sisters is UNTESTED - and the pattern is exactly why it must be tested rather than assumed. An eighth tie runs through the Bothas: Susanna Johanna married Jan Hendrik BothaL, whose mother was a HESTER VENTER.

THE TIMING IS TIGHT. The Venter marriage of October 1807 and the Strydom marriage of March 1808 are FIVE MONTHS APART, and the father died in April 1809. The two alliances were made in the last eighteen months of his life and were still being made fifteen years later.

WHAT IT EXPLAINS: Rondabel. David Jan StrydomM held it from 1841 and it was with Jan Adriaan OosthuizenL by 1868 - and David Jan was married to Jan Adriaan's AUNT. See STO-0043.

[17 Sep 2026] DE VILLIERS (SRC-656, Deel 2, OOSTHUIJZEN p. ~511): 'Ockert, gedoopt 9 Februari 1755, burger te Swellendam, gehuwd 26 Januari 1788 met Johanna Catharina van Tonderen'. The day and month of the marriage agree with UNI-000014 (1783-01-26); the year 1788 is very likely an OCR misreading of 1783. The bride's name disagrees with the book's own van Tonderen entry, which marries SUSANNA Catharina (baptised 20 Feb 1763) to Ockert Oosthuijzen, and with the baptism registers (SRC-515). A slip in the book or the OCR; the registers stand.

[22 Sep 2026] *** IN THE KAMMANASSIE IN JULY 1799 (SRC-661, EVT-000344). *** Records of the Cape Colony vol. II prints a letter signed 'Okker Oosthuyzen' (pp. 449-450) reporting the Khoikhoi rising, and the Lange Kloof field cornet P.H. van Rooyen names 'O. Oosthuyzen and B. Lindeque in the Cammasie' and says 'Okker Oosthuysen lives only at the distance of half a day's journey on horseback from here'. Very probably this man [TO VERIFY]: it places his household in the Kammanassie / upper Olifants country nine years before the Swellendam baptism of 1808 ('woonende aan Oliphants Rivier') and ten before his death at de Modder Fonteyn.
