18. Maria Wilhelmina Hoornik-Pellers and
Pieter Hoornik had a total of ten children.
Sien was the oldest child in this Catholic family. After her father’s death in 1875, ‘the chairmaking business of
Pieter Anthonie, the oldest son, supplemented what Sien and her mother could earn as seamstresses and charwomen, but in general the Hoorniks were poor and depended on public assistance or church charity ... For a time Sien and three of her brothers lived in the Catholic Orphanage as there was no adequate way to provide for them at home.’ Sien ‘relied on prostitution to survive’. See Zemel 1987, p. 353.
