I have a note here, but no book number and I don't have any more info than this: Marriage record from Amsterdam (Netherlands): 21 July 1621. Philippe Dutrieux of Roby aged 34 and living in the Runtstreat, worsted dyer, widower of Jacquemyne Noiret, to Susanna du Chesne, of Sedan aged 20 years, orphan, assisted by Jean Pinson her cousin. This would make Susanna du Chesne's age about 44 at the baptism of Jacob du Trieux on 2 December 1645. While Susanna is old enough to be a grandmother in 1645, it's still entirely possible to have children at age 44 and beyond. Adult males can father children at almost any age. Did Isaac or Jacob du Trieux name any daughters 'Jacomyntje'? Thanks, Liz J
