Others of the same name

Afrikaans naming repeats hard, and the Cape Dutch naming pattern reuses a name on purpose, a child who died young has the name given again to a later sibling. These are different people. Never match on a name alone.

Research notes

[TREE] Added 2026-07-31 by kin_sweep.py under the one-degree rule: child of Adriana Cecilia OosthuizenL (b.1816). Thin record, name, dates and the family link only. NO PLACE IMPORTED: the tree's place strings are systematically wrong and are not evidence.

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.

Open questions

Duplicate candidates from the one-degree pull, settled on FamilySearch ids priority 2 · LEAD-0035
38 people added on 31 Jul 2026 share a name AND a birth YEAR with somebody already in the model, and 32 share a name with no date at all. Are they the same people?

What would settle it A full birth or baptism date on either side of a pair. Name plus YEAR is not enough here and must not be treated as enough.
