A sourced gap beats an unsourced fill. These are the open questions on this person, stated rather than papered over.

Open questions

• Which Oosthuizens came to the Koup, and where did the ones who did not go? priority 2 · LEAD-0214

  Ockert (1755) x Susanna Catharina van TonderM had eighteen children. One of them, Ockert Almero (1786), is the root of everything this project holds. What happened to the other seventeen - who stayed in the western Cape, who went to Hanover and the northern frontier, who joined the emigration of 1838?

  What would settle it A branch-by-branch destination for each of the eighteen, each one resting on a dated record - a baptism, a death notice, a grave - rather than on a family-tree place string, which 5 says is systematically wrong and must not be used as evidence.
