Haarlem Patrician Link — Preparation (Pending Confirmation)
This preface tracks the possible connection from the Haarlem patrician family (Mattheus van Valckenburgh × Agatha van Loo) to the later civic line. Evidence is promising but not yet fully scan‑verified. Do not yellow‑dot this section until the 1714 poorter folio and the 1688 baptism scan are confirmed.
- Candidate Patriarch: Mattheus van Valckenburgh († c.1695), councilor/pensionary of Haarlem. [scan pending]
- Candidate Son: Jan van Valckenburgh — recorded as poorter in Haarlem (1714), stated son of Mattheus. [poorterboek entry pending]
- Bridge to Civic Line: Cornelis van Valckenburgh (m. 1737, Haarlem) appears as native poorter (1744); likely father of Lambertus (bapt. 1742). [DTB marriage scan pending]
Record Type(s): Poorterboeken (Haarlem), DTB baptisms & marriages (Reformed), Amsterdam ondertrouw registers.
Prepared by: Eric Graham with ChatGPT (Appendix G format). Audit note: Patrician link under active verification; hold yellow dot.

- Marriage: To Aaltje Pieters, 22 Jun 1737 (Grote Kerk, Haarlem). [DTB scan pending]

Generation E — Lambertus van Valkenburg (b. 1742) × Maria van der Hoven (ondertrouw 1758, Amsterdam)
Fact Sheet
Backbone
Lambertus, described as “jongeman van Haerlem,” marries Maria van der Hoven in Amsterdam in 1758. This record explicitly carries the Haarlem origin forward and begins the family’s Amsterdam period.

Generation D — Goosen (Gosen) van Valkenburg (bap. 4 Mar 1759, Oude Kerk) × Petronella Jacobse van Veen (m. 15 Jun 1785)
Fact Sheet
Backbone
The 1785 ondertrouw for Goosen ("jongeman van Haerlem") and Petronella van Veen is the lynchpin document: it names both fathers as witnesses and locks the Haarlem‑to‑Amsterdam continuity.

- Ondertrouw/Marriage: 14 May / 15 Jun 1785, Amsterdam (Oude Kerk). [scan pending]
