Willem Johannes Jooste Sr

I · The Instruments

Eight instruments, nineteen months, two governments

The file gathers every instrument the Master's Office processed for G5's estate between the Sterfkennisgewing of May 1889 and the Final L&D Account close in December 1890. Two governments touch the file: the South African Republic (Z.A. Republiek) administered the estate through its Master's office at Pretoria; the Cape of Good Hope Master's seat at Worcester registered the underlying Joint Will (No. 472). Nineteen months of administration is exceptionally rapid for a Transvaal probate of this size — a signal that the widow's remarriage trigger in the Will was activated. The Weeskamer Remarriage Permission Certificate of 17 December 1890 confirms it: F. J. Joost geboren Carr remarried into the Geldenhuys family twelve days before the Final L&D Account closed.

A note on the languages

The principal instruments — Sterfkennisgewing, Testament, Inventaris, both L&D Accounts, Power of Attorney, Weeskamer Certificate, and the duplicate Will — are written in Hollands, the formal Dutch legal language that served both the Cape Colony and the South African Republic into the early twentieth century. The handwriting is dense Cape-Dutch cursive of the 1880s, with the characteristic loose d/t alternation that turns the family name across Joost, Joosde, Joosten, and Jooste in the same document. The only English text in the file is the typewritten 1907 supplementary instrument concerning the sale of Erf No. 123 — a later post-Anglo-Boer-War addition by the executors.

II · Instrument I — The Sterfkennisgewing

Potchefstroom · 5 May 1889

The Sterfkennisgewing names Willem Johannes Jooste Sr in the deceased field, born at Tulbach, Cape Colonie, of the parents Jacobus Petrus Jooste and Alida Susanna Theron. He was 60 years 11 months 5 days at death — a precise figure typical of Cape-Dutch sterftekennis writing. His occupation, in field 5: Particulier. His marital state: married, in community of property, to Frances Johanna Carr. He died at Potchefstroom on 5 May 1889 of natural causes after a brief illness.

The Death Notice carries a critical correction to the xlsx-tradition reading of his parents. Family tradition recorded G6 as "Pieter Cornelis Jooste, born c. 1789 Tulbagh" + "Martha Elizabeth Visser". The primary source contradicts both. The 1889 Sterfkennisgewing in his widow's hand confirms G6 as Jacobus Petrus Jooste + Alida Susanna Theron — the WikiTree Jooste-692 ancestors-page rendering. The xlsx Pieter Cornelis 1788 entry remains undisposed — possibly an alternate-line ancestor; possibly a transcription error from an earlier source.

Particulier — what it meant

At the South African Republic register, Particulier indicates a propertied-investor classification: someone whose primary identity at law was as the holder of capital — land, shares, debts owed — rather than as an active labourer or farmer. The Inventaris and L&D Accounts that follow corroborate the classification beyond any doubt. G5 held five farms across the Potchefstroom and Klerksdorp districts, 2,500 shares in the Potchefstroom Mining-Syndicate at a peak-rush 11/- per share, additional holdings in four sister mining and steam companies, and a lending portfolio that recorded promissory notes and bonds owed to him by neighbours and relatives across the Vaalrivier corridor. He had transitioned, in his own lifetime, from the farmer ancestry of G6–G9 into the propertied class.

The 8 children

The Sterfkennisgewing's field 12 lists the surviving family. Eight children survive G5 at his death:

III · Instrument II — The Testament

Worcester No. 472 · 1 January 1889

Worcester — the Cape-side legal anchor

The Joint Will is registered at Worcester No. 472, in the Cape of Good Hope. The same Worcester anchor appears at G4's 1906 estate — his Joint Will with Elizabeth Magdalena was also signed at Worcester in the 1880s. This is a multi-generation Cape-side legal-seat pattern that persisted across the family's Cape→Transvaal migration. Possible explanations: a family attorney in Worcester served the extended family across generations; or the family retained Cape-side property (perhaps inherited from G6's Land van Waveren holdings, near Worcester) that required Cape Master's office handling; or the Mouton family (Maria Mouton, wife of G9 Frans Joosten in 1706, was Cape-Huguenot) had attorney connections at Worcester that the Joost-Mouton extended family continued to use. Closing the Worcester anchor question is research opportunity OPP-265 in the project's pipeline.

The structure of the Will

The Joint Will has five distinct sections, each captured at a different image:

IV · Instrument III — The Inventaris

Potchefstroom · 14 May 1889

The portfolio at a glance

The Inventaris itemises the gross estate at £22,316. The structure of the holdings:

The portfolio is the substantive evidence for the Particulier classification. These are not the holdings of an active farmer: they are the holdings of a man whose primary economic role at his death was managing a diversified capital portfolio across farms, mining-syndicate shares, and lending. The Klerksdorp gold-rush — discovered in 1886, peaking in 1888–1890 — is the substrate context for the mining-syndicate participation. G5's Klerksdorp 20 October 1888 private deed and the 1 December 1888 Rietfontein sale to his eight children both occur at the rush's peak.

V · Instrument IV — The First Liquidation and Distribution Account

Potchefstroom · 26 October 1889

The numerical chain

From the gross Inventaris total to the Final Balans, the numbers reconcile through three stages:

The two L&D Accounts — 26 October 1889 first, 29 December 1890 final — bracket the activation of the remarriage-trigger clause and its consequences.

VI · Instrument V — The Final L&D + The Geldenhuys Trigger

Potchefstroom · 29 December 1890

The 12-day window

Between 17 December 1890 and 29 December 1890, three events compress into twelve days:

The nineteen-month total administration — from May 1889 Sterfkennisgewing to December 1890 Final L&D close — is rapid for a Transvaal probate of this size. Ordinary administration runs 12 to 24 months. The compression here is the trigger doing its work: the Will's clause forced a faster settlement once the remarriage was contemplated, and Fanny + her co-executors moved the file accordingly.

VII · The Rietfontein No. 632 Sale

1 December 1888 · Schoonspruit, Potchefstroom · Eight children, in shares

The sale at primary source

From the duplicate Will, image 887: "De Testateuren verklaren verder dat op den 1^sten December 1888 de plaats Rietfontein N^o 632 gelegen in de wijk Schoonspruit district Potchefstroom door hen is verkocht in termen alsoo is overeengekomen, aan hun kinderen met name: Willem Johannes Joost (Jr) — Carl Willem Joost — Jacobus Petrus Joost — Robert Johannes Joost — Pieter Jacobus Joost — Alida Susanna Humphries gebooren Joost — Susanna Johanna Carr gebooren Joost — Sarah Gertruida Winstanley gebooren Joost."

Eight children, named at primary source by their married surnames, named co-buyers of the family's principal Potchefstroom-district farm — five months before G5's death and on terms the testators set themselves. The transaction precedes a private deed at Klerksdorp on 20 October 1888 (24 October per the duplicate Will). The timing is consistent with G5 settling the family's principal land asset onto the next generation in anticipation of his own death — and using the same instrument to establish the £1,000 trust for the Humphries grandchild and to set G4's eventual trustee role over that trust.

What the misread cost — and what corrected it

Earlier readings of the original Will at image 876 inferred a sale of Hartebeesfontein No. 590 to a son-in-law Hartzhof. That reading propagated into the project's §3.3 Land Arc model — which made the further inference that G4's eventual 1/8 share of Hartebeesfontein No. 590 at his 1906 estate had come through this Hartzhof son-in-law route. None of that is supported by the primary source. The duplicate Will at images 885–890 cross-validates the correct reading. The farm is Rietfontein No. 632. The buyers are eight children. There is no Hartzhof son-in-law in the buyer list. (A J.B. Hartzhof appears later in the file as a witness at the duplicate Will closing — distinct from any buyer or son-in-law role.) G4's 1906 Hartebeesfontein No. 590 1/8 share has a separate chain — not yet documented in SRC-2026-035; research opportunity OPP-259 (Klerksdorp Deeds Office title-chain).

Mineral rights preserved

The sale recital preserves mineral rights at equal share for all eight children. At the Klerksdorp gold-rush peak — 1886–1890 — this was a material consideration. The Potchefstroom Mining-Syndicate, Polchefstroom Steam Fields Co, Hardbreed Union, Norigskool Cabuon, and Vaalrivier — five companies G5 held shares in — were all operating in the same Vaal corridor where Rietfontein, Wilgespruit, and the other family farms sat. The eight children's reserved mineral rights at Rietfontein were a continuing economic interest, not a paper formality.

VIII · Instrument VIII — The Duplicate Will

Bound into the file · attested as a true copy · images 884–890

What the duplicate disclosed

The duplicate Will at images 884–890 is the cross-validation instrument for the original Will at images 873–877. It is what caught the Rietfontein-vs-Hartebeesfontein misread. It also documented several substrate points the original alone did not make clear:

• The Alida Susanna Humphries divorce-or-death alternative clause — if her Humphries marriage ends, her Rietfontein share reverts to siblings and she receives £100 per year as annuity bequest.
• The G4 trustee role over the £1,000 Humphries grandchild bequest activates only after both testators are dead — not at G5's death alone. At G5's 1889 death, Fanny was alive; G4's trustee role would not activate until Fanny's death (post-1905, per Geldenhuys remarriage).
• The Klerksdorp private deed date is read as 24 October 1888 in the duplicate, against 20 October 1888 in the original — substrate-uncertainty at the deed date that the duplicate did not finally resolve; cross-validation pending Klerksdorp Deeds Office research.
• The witnesses at the duplicate Will closing — A.K. Hisenbach and J. van Eck — confirm the witness identification at the original Will. A.K. Hisenbach is the same Hisenbach who held £1,000 promissory + £1,000 receivable across the file. The Hisenbach connection at the family's Potchefstroom social and business network is three-instrument substantial.

IX · The Family — Three Generations Visible

G6, G5, G4: parents named at primary source for the first time

The G5 1889 file is the first document in the project's primary-source substrate to name G6 — Willem Johannes Sr's parents — at primary source. The Sterfkennisgewing's field 3 (Namen der Ouders van den Overledene) records them in Fanny Carr's hand on the day of G5's death. The xlsx family-tradition reading was wrong at G6 generation; the primary source corrects it.

Carriers — what the marriages brought in

The G5 family carriers across generation are:

• Theron — at G6 (Alida Susanna Theron 1793, mother of G5). Cape-Huguenot line.
• Carr — at G5 (Fanny Johanna Carr, G5's wife). Possibly Worcester-Cape origin; substantial in-family network (Johannes Carr witness at Will; Carel Johannes Carr m. Susanna Johanna Joost; F.D. Carll creditor at L&D; Geldenhuys remarriage).
• Humphries — at G5 daughters (Alida Susanna m. John William Humphries Sr; their son J.W. Humphries Jr is the grandchild beneficiary). The Humphries family appears repeatedly: G3 also married a Humphries (Elizabeth Magdalena Jooste born Humphries per the 1907 supplementary document). The Humphries connection across G4–G5–G3 is substantial.
• Winstanley — at G5 daughter (Sarah Gertruida m. Winstanley).
• Carr (second) — at G5 daughter (Susanna Johanna m. Carel Johannes Carr; later m. Jan Gysbert Carr).
• Geldenhuys — at G5 widow (Fanny Carr → Geldenhuys, 1890). Cape-side stamouer line.
• Hisenbach — at G5 social network (witness, creditor, debtor; not a marriage but a substantial economic + social connection at Potchefstroom).
• F.P. Joost — at G5 family (relative, undetermined; multi-instrument debtor at £2,500+ exposure). Possibly G5's brother or cousin.

X · Provenance & Methodology

How this reconstruction was made

Source

The G5 1889 MHG file is held at the TAB Transvaal Archives Depot within the National Archives of South Africa (NARSSA) in Pretoria. It forms part of the Master of the Supreme Court of the Transvaal — Probate Estate Case Files 1869–1961 collection (FamilySearch collection 2520237). The file occupies images 872–891 of the microfilm-scanned volume 007805276, Item 5, titled "Transvaal. Probate Estate Case Files 1889". The case reference at the file spine is 4602/89.

The volume is accessible via FamilySearch at the image-viewer ARK 3:1:3Q9M-CS92-69G6-7. The personArk for G5 indexed metadata is 1:1:Q2DG-RCXL. Access requires a FamilySearch account; the file viewer requires authenticated session.

Method

85 captures of the file were made at full Retina resolution (2560×1656) by the founder using macOS Cmd+Shift+4 selection screenshots from the FamilySearch image-viewer. Coverage spans images 872–891 — Sterfkennisgewing, full Joint Will, Inventaris, both L&D Accounts, Power of Attorney, Weeskamer Remarriage Certificate, duplicate Will, and file-close spine.

The captures were transferred to the canonical SRC-2026-035 source directory and renamed by FamilySearch image-number (the original chronological-capture-order naming had drifted from FS image-numbers across the 20 images; the rename pass at iter 4 phase 3 corrected the naming convention to match FS image-numbers).

The Hollands cursive transcription was made jointly: the agent transcribed at cursive-vision tier; the founder verified at full-Retina view where readings were uncertain. Several substantive readings — Rietfontein vs Hartebeesfontein, the 9-share supplementary clause interpretation, the witness identification at the duplicate Will, the children's married surnames — were resolved through cross-validation between the original Will and the duplicate Will bound in the same file. Where reading uncertainty remains, [bracketed annotations] mark the substrate-uncertainty register.

Reconstruction at substrate-citation depth

The full reconstruction is published as source.md at SRC-2026-035 in the project's canonical source-storage — approximately 6,000 lines of Hollands-to-English transcription, analytic substrate, cross-validation, and honest caveats. The directory: /heraldry/60_research/sources/items/SRC-2026-035/. The page-images are at SRC-2026-035/page-images/, renamed per FS image-number with sequential cap-numbering within each image bucket.

Architectural altitude

The G5 file is the deepest single-source primary substrate the project has engaged at any generation — substantially deeper than the G4 1906 file in single-source coverage (~6,000 lines of source.md against G4's ~900). The Asset Arc inflection visible in this file — the transition from farmer-G6 ancestry to diversified-portfolio Particulier — is the generation at which the family wealth crystallises. Combined with the G4 1906 file at SRC-2026-034 + the G9 1714 Cape MOOC + the G9 1706 Bartolomeusklip first-asset amassed at the Mouton marriage, the project now has primary-source substrate at four generations across two centuries of Cape-and-Transvaal history.
