From the list of DTB entries for this couple, I gather that they had 5 kids, two of whom died quite young, since Agatha died the same year that Archibald Jr. was born, probably from complications arising from the birth of Archibald. At her death, there were only 3 children still living. These would be the baby Archibald, young Lucia of six, and Agatha Maria who was two. Archibald Jr. went on to do great things for the WIC and politics, while Lucy married a Haarlemmer and died in childbirth. The youngest daughter remained a spinster, probably frightened of childbirth since her sister and mother had problems. She apparently never left home as her address at death was Haringvliet.
Lucia Hope 1741-1765 Zachary's daughter married the son of his Haarlem associate André/Andries Heshuysen/Heshuijsen.
The DTB registers of Rotterdam and Haarlem tell her sad story, not uncommon at the time. She was married to a young man of promise who had just come into his own after his father’s death, and she died the next year.
Adolf Jan Heshuijsen’s father André had been a successful merchant in Haarlem with 10 children born to him by Louise Visscher.
The wedding of Jan Adolf and Lucia has three entries in the Rotterdam archives: betrothal and wedding in Rotterdam, and church blessing in Delfshaven, showing the importance.
