Maria Thins

Maria Thins (c. 1593 – 27 December 1680) was the mother-in-law of Johannes Vermeer and a member of the Gouda Thins family. She was raised in a devout Dutch Catholic family with two sisters and a brother. Outliving her parents and siblings, she received inheritances over the years, making her a wealthy woman. She married a prosperous brickmaker, Reynier Bolnes, in 1622. They had three children together, Catharina, Willem, and Cornelia. By 1635, Bolnes verbally and physically abused his wife and daughters. Thins moved to Delft with her daughters. Her son Willem stayed with his father. Thins was a wealthy woman due to the separation settlement of her husband in 1649 and the estates she inherited from her family.

Her daughter Catharina married Johannes Vermeer, an artist, art dealer, and operator of the family's inn in Delft. Vermeer and Catharina lived at Thins house by 1660. The couple had fifteen children, four of whom died in infancy. Raising nearly a dozen children strained Vermeer financially. He relied on the support from his mother-in-law. During the Franco-Dutch War (1672–1674), Vermeer became impoverished. Thins reduced the money she provided to Catharina and her husband due to the loss of income during that period. Vermeer died in 1675, and Thins died five years later. Catharina was the only one of Thins' children to survive her. Thins drew up her will to maximize what she could provide for her grandchildren and their education, while limiting how much might be taken by Catharina's creditors. Catharina died in 1687.
