Jacoba Bicker

The protagonists of the patriciate were closely related,[2] and in 1663, at the age of 22, she married her other cousin Pieter de Graeff at Ilpenstein Castle.

[3] The poets Jan Vos,[4] Joost van den Vondel[5] and Gerard Brandt,[6] who were present, "sang about" this wedding.

The couple had three children:[2] In 1663 Jacoba Bicker was painted together with her husband Pieter by Caspar Netscher and alone by Jurriaen Ovens.

When her sister Wendela died in 1668, her husband Pieter and her brother-in-law Jean Deutz were appointed guardians of their nephews and nieces and were responsible for handling the estate.

[8] In 1695 Jacoba Bicker was one of the 250 richest persons from the Dutch Golden Age and was assessed for a taxable capital of 491,811 guilders.
