Event EVT-000161

Two Dutch baptisms are tested against the children, and both fail

31 March 1675 · disputed

[SRC-101, SRC-102] Two candidate baptisms for the stamvader survive - Amsterdam, father Johannes Oosthuijsz and mother Catrina Bouwmans; and Leiden on this day, father Johannes Oosthuysen and mother Antonette de Rede. Both were tested against the names he gave his own nine children, using a pattern this family is shown to follow strictly. Both fail: each would require an eldest son named Johannes, and his eldest son was GERHARDUS. The names he actually used predict parents called GERHARDUS and BARBARA - and those are Rhineland names, which is where his will says he came from. Dated to the Leiden record because the Amsterdam one carries no visible date. | [1 Aug 2026] SCOPE CHANGED to 'disputed' and this event is now OFF THE TIMELINE: "parentage of the first oosthuizen is not clear. leave it out of timeline." He is right, and the reason is in this row's own text: the date 31 March 1675 is the LEIDEN baptism - one of the two candidates this event exists to DISPROVE - chosen only because the Amsterdam record carries no visible date. So the chronology was opening, at its very first line, on a date belonging to a claim we reject. The event is kept in full because the test is worth having on the record; it simply is not a thing that happened in this family's history, and it still appears on the pages of PER-000319 and PER-000320, which is where it is useful.

Everyone the record names at this occasion. Who stood together is the clearest surviving evidence of which families were close to which, if you know of others who were here, this is the page they belong on.
