8 October 2026 — Keyser original-record research, fourth round

One of the two youngest sons, for whom learning a trade was directed. Dirck Keyser’s will of 2 January 1756 and codicil of 4 January, proved 4 February, name the seven-child group. This corroborates the father link for the corresponding existing compiled profile. Exact birth/death dates still rest on the earlier compilation; the will does not explicitly establish maternity.
