Notes for Aert Drieszn van Os: Aert Andries van Osch died sometime before 1695 leaving behind his widow, Teunisken Hendricksdr Boom and two children, Andries and Joostie. Teunisken then remarried, and she and her husband, Hermen Zegerszn, entered into an agreement in which they co-mingled their property and stated that upon their death, all children born of both this and the previous marriage should share this inheritance equally. In addition, they promised to raise and care for the two children until their majority, providing them with clothing, food and drink, in addition to providing proper training for a trade. By Dave Pol.
