Jan Cornelis Haaxman
Jan Cornelis was a grocer who lived on the corner of the Jacob Gerritsstraat at the Spiegelsbrug. He was active in the community as a lieutenant of the 2nd and 3rd quads of the 2nd Witte Vendel of the civic guards from 1707 to 1716. In March 1713, he became a member of the Reformed Church (HGD inv. 469 fol. 15). In 1716, he paid 5 guilders for the family tax (familiegeld OAD inv. 680 fol. 45). In 1719, he became a district supervisor (wijkmeester).
The day before their marriage on July 20, 1709, Jan and Aletta made a pre-nuptial agreement in Den Haag, Johan van der Burch notary. Three weeks later on August 12, they made a will, Cornelis van der Sleyden notary. Seven months later, they made another will with the same notary on March 7, 1710. In both wills, Jan is described as healthy and Aletta as bedridden. In the March 1710 will, they declared the two previous documents null and void, they seemed to be making provisions for Aletta's death, although they also explained how they wanted their children raised in the event of their deaths.
As it turned out, Aletta and Jan had six children. Jan died when she was pregnant with the sixth. The baby was named after his father, but he died a month later.
Leeuwenhoek named Jan in his will of November 17, 1721, just a month before Jan died. The burial record notes that he was living in the little house next to a windmill for grinding colouring materials (verfmolen) outside the Oostpoort on the east side of the Crommeheul (also Kromme Heul) over the Kromme Watering along the Delfgauwse Vaart that he purchased on December 14, 1719, Jan de Bries notary. Aletta paid the 1733 and 1756 taxes on the property (verpondingen) and lived there until her death in 1757.
Jan's portion of Leeuwenhoek's estate passed to his four surviving children: Maria, Adriana, Cornelis, and Dirk.

Their great-grandson Peter Jacob Haaxman, born in Rotterdam in 1810, wrote a biography of Leeuwenhoek in 1875.
