A life in the record

1. 1751–1805 event In the Swellendam district on the rolls
   Half a century of opgaafrollen count this line in the Swellendam district: Jacobus Oosthuijsen and Dina Brits from 1751, four Oosthuizen households together on one folio by 1760, and Ockert Jacobus's own household to the 1805 roll. A DISTRICT is what a roll pins, so this waypoint is labelled for the

4. 26 January 1783 event Ockert Jacobus Oosthuizen marries Susanna Catharina van Tonder at Swellendam
   The marriage the Modderfonteyn household grew from - twenty-six years and three months before the estate was inventoried on the farm, which is the outer bound of how long the family could have held it (LEAD-0299).
5. 11 May 1786 event Ockert Almero Oosthuizen baptised, with Venetian noblemen as witnesses
   [SRC-076] Born 25 April 1786, baptised 11 May as "Ocert Almaro".

Open questions

• Find OCKERT JACOBSZ with wife S. C. VAN TONDER on the Swellendam roll - and read his farm priority 1 · LEAD-0234

  Film 008145384 is a SWELLENDAM opgaafrol carrying a FARMS column. Ockert Jacobus OosthuizenL (PER-000118) died at de Modder Fonteyn in April 1809 and married Susanna Catharina van TonderH on 26 January 1783. Which entry is his, and what farm does the roll give him?

  What would settle it An entry reading Ockert + Jacobsz with a van Tonder wife, and the farm written against it on the right-hand leaf.

• Put a ruler across the 1805 opening: whose farm is Modderfontyn? priority 1 · LEAD-0246

  Image 41 of film 008145384 carries Oosthuizen entries 776-790, among them 784 OCKERT with Susanna Catharina van TonderHen and 789 OCKT: ALMERO. The facing leaf, image 42, carries the farm column: de Wolve Fonteyn, aan d' Vals Rivier en d' Berg Rivier of Fo[ntein], de groote Heuvel en d' Buffels Fo[ntein], MODDERFONTYN, Voorbaat, Riet Valey. Which farm row reads across to which entry?

  What would settle it A ruled line traced from an entry number on the left leaf to a farm row on the right leaf. Nothing less. The two leaves currently held are screenshots at different zooms.

• The 1805 roll counts this family's children, and the model disagrees priority 1 · LEAD-0247

  Entry 784 of the 1805 Swellendam roll gives Ockert Jacobus OosthuizenL and Susanna Catharina van TonderH SIX and FOUR under sixteen. The model holds eighteen children for them, of whom the ones born after March 1789 are four sons and six daughters. Six-and-four against four-and-six is an exact swap. Which is right?

  What would settle it The full column heading, plus a baptism for each of the three doubtful daughters. Either two baptisms in different years for one name, which makes them two children, or one, which makes the second row a duplicate.

• Did two Oosthuizen brothers marry two van Tonder sisters? priority 2 · LEAD-0231

  Ockert Jacobus OosthuizenL (PER-000118) married SUSANNA CATHARINA VAN TONDER on 26 January 1783. The opgaafrol index at SRC-482 shows another Oosthuizen household, entry 430, headed by a GERRET with the wife JOH: VAN TONDEREN. Are the two wives sisters, and is that Gerret one of Ockert's brothers?

  What would settle it A baptism or marriage record naming both van Tonder women as daughters of the same father, together with the Gerret of entry 430 identified by patronymic.
