Jacqueline Antoinette Marie Catherine Van der Vyvere

Spouse. Jean Pierre Le Claire (1718 – 1793).

Married Jean Pierre Le Claire (1718–1793).

Children. Mother of Théodore François Joseph Leclaire (1752–1811), Louis Jean Baptiste Leclaire (1753–1825) and Marie J. A. Leclaire (1755–1830).

Jacqueline Van der Vyvere brought substantial wealth and prestige into the LeClaire family. Family tradition records a dowry of approximately 90,000 livres, a figure suggesting exceptional resources by eighteenth-century standards. Through her descendants, the Van der Vyvere inheritance became intertwined with the later military and LeClaire family branches.

Born into the Van der Vyvere family in 1726, she was the mother of Général de Division Théodore François Joseph Leclaire and of Louis Jean Baptiste Leclaire, the direct ancestor of the modern House. She died in 1789, shortly before the outbreak of the French Revolution.

The Van der Vyvere marriage stands as one of the strongest indicators of wealth within the documented family history. A dowry of approximately 90,000 livres would, in eighteenth-century Europe, have been associated with major merchants, financiers, office-holders or noble families.
