She worked there until 1853, when she moved to Oosterbeek and joined a group of Painters known as the Hollandse Barbizon. In 1863, her friend, Adriana Johanna Haanen, the sister-in-law of her Teacher, Kiers, joined her there. Seven years later, they built a home known as the "Villa Grada", where they gave drawing and painting lessons. Haanen died in 1895, but Vos remained and became one of the last artists in residence there. On her eightieth birthday, she received a personal tribute from seventy members of Arti et Amicitiae.
