Research notes

Tokkie's son; owns Rondable/Oude Muure/Kopjes Kraal (valuation roll)

29 Jul 2026 [SRC-074] FamilySearch names him GERT Jan OosthuizenM Marincowitz, not Gerhard Jan [TO VERIFY] - he is named for his grandfather Gert Jan (PER-000023).

[31 Jul 2026] MERGED PER-000451 into this row. Both rows carry FamilySearch id GXG5-B6S, so they are one person. Kept PER-000024 ('Gerhard Jan Oosthuizen MarincowitzH'); merged PER-000451 ('Gert Jan Oosthuizen MarincowitzL'). Exposed by the _FID backfill of 31 Jul 2026, which gave nearly every person an id to collide on; before that these had no shared key. Check GXG5-B6S on FamilySearch before assuming the upstream tree needs anything - it is usually the LOCAL tree that is stale (LEAD-0021). Moved across: tree id=. DISAGREEMENTS, kept rather than resolved - the FamilySearch id settles these in one click: display_name: kept 'Gerhard Jan Oosthuizen MarincowitzH', PER-000451 said 'Gert Jan Oosthuizen MarincowitzL'; given: kept 'Gerhard Jan OosthuizenM', PER-000451 said 'Gert Jan OosthuizenM'.

[16 Aug 2026, FAMILY] CALLED OOSTHUIZEN, by his second given name. Frans names him that way in placing MED-000111: "Oosthuizen on the right." It is an unusual noemnaam and a telling one - the Oosthuizen surname carried into this family as a given name by his grandmother Anna Margaretha OosthuizenM, and then used as the everyday name for the man. 5b: record it, do not normalise it to Gerhard.

These are working notes, not finished prose: they carry the reasoning, the corrections and the things still marked to verify. They are kept here so the page itself can read as what is known.

What the record is missing

“F.S. Marincowitz” held ground next door and we have no tenure for them third order · B4 unheld-owner
A boundary description for Botterkraal (Jansenskraal No. 104 Ptn 2) names F.S. MarincowitzM, a surveyor stating on the record that this person held the adjoining ground. We do hold Marincowitz tenure elsewhere, but none on this boundary and none at this date.

What would settle it The diagram's own date fixes the window. The quitrent or erfpacht register for that year names the holder of the adjoining place, and an estate inventory will name the farm outright.

Found by breaks.py reading the model against itself, not written by hand, each one is a shape of missing record, not a fault in the data. The whole set is on the questions page.
