Evidence

Between 1869, seven years after Valck took up his first post in Java, when his daughter in the Netherlands could not yet read and had just turned six, and 1892, when he died in The Hague and she was by then Susanna Antoinette Valck Lucassen—married to her deceased mother’s nephew, mother of three, and daughter-in-law in residence on the Kemanglen estate—he wrote to her monthly and she, as a young woman, bimonthly to him. — Ann Laura Stoler, Along the Archival Grain_ Epistemic…, 1317
