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

[FamilySearch, 29 Jul 2026] Eldest brother of Almero Jacobus Hitge OosthuizenL (PER-000016).

[31 Jul 2026] MERGED PER-000642 into this row. PROVEN DUPLICATE, resolved on the FamilySearch id. Both rows carry GQKX-JX7; an FS id names one person, so these are one person recorded twice. Created by the 31 Jul 2026 one-degree tree pull, which matched on tree id alone - and 255 model people carry no tree id, so any of them one hop from a tree-linked person was added again. Survivor is the pre-existing row; it carries the prose, sources and land links. Moved across: tree id=. DISAGREEMENTS, kept rather than resolved - the FamilySearch id settles these in one click: display_name: kept 'Jan Adriaan OosthuizenL (b.1864)', PER-000642 said 'Jan Adriaan OosthuizenL'; birth_edtf: kept '1864', PER-000642 said '1856'; death_edtf: kept '1950', PER-000642 said '1936-01-30'.

[5 Aug 2026] THIS ROW'S DATES AND ITS TREE ID DO NOT DESCRIBE THE SAME MAN, and the 31 Jul merge note above is wrong to call the disagreement settleable in one click. The private tree's - the id this row carries - reads b. 1856, d. 30 Jan 1936 at Pretoria. The row reads b. 1864, d. 1950. Those are PER-000398's figures (tree, b. 30 Aug 1864, d. 11 Dec 1950). The 31 Jul merge kept this row's dates and took the other row's tree id, so the row now points at a tree record that contradicts it. Two further things the tree shows, found 5 Aug: BOTH tree records are married to a Johanna Susanna De VilliersH born 3 August 1867 (families and), which one woman cannot be unless the two men are one man duplicated upstream; and this row's own opening note - 'eldest brother of Almero Jacobus Hitge OosthuizenL (PER-000016)' - describes PER-000398's parents (PER-000005 x PER-000139), not the parents kin_sweep gave this row. NOT MERGED. A birth eight years apart and a death fourteen years apart in a different province is a disagreement, not a precision, and the project has been wrong about an Ockert Almero pair on thinner evidence than this.
