Research notes
[SRC-074] Son of PER-000208. The FamilySearch spelling keeps the trema: Oosthuÿsen.
[31 Jul 2026] MERGED PER-000577 into this row. PROVEN DUPLICATE, resolved on the FamilySearch id. Both rows carry GK37-MZV; 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=. Dates sharpened from the merged row: birth_edtf 1849 -> 1849-02-05. DISAGREEMENTS, kept rather than resolved - the FamilySearch id settles these in one click: display_name: kept 'Jacobus Johannis OosthuÿsenH (b.1849)', PER-000577 said 'Jacobus Johannis OosthuÿsenH'.
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.

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.
