This Stuart family was supposedly descended from an Archibald Stuart who had been herald at the court of Mary Stuart, Queen of Scots. Archibald's supposed son Jacob Stuart (±1554-1622) left St. Andrews, Scotland, for Bergen op Zoom, The Netherlands. He married 3 times and left many descendants.
On June 18, 1647, in Zierikzee, The Netherlands, Mary Stuart married Willem de Clercq (±1620-1657), son of Lieven de Clercq and Maijken Imants. Willem was a resident of Poortambacht near Zierikzee. Mary Stuart died in Zierikzee in 1656.
