According to Houbraken she was the daughter of Matthijs Wulfraet who travelled to Frankfurt and became a respected portrait painter, painting many visiting dignitaries and important citizens.
He reached a great age, and was able to teach his daughter Margaret his art, which she performed well.
[1] Houbraken was planning on devoting a page to her memory, but he never got around to it, since he died before he reached her birth year in his three-volume work on biographical sketches of painters of the Netherlands.
[1] Her biography was included in Jan van Gool's sequel, accompanied by a portrait based on a drawing of one of her self-portraits sent to him by Gerard Melder.
[2] She was popular in Amsterdam and according to Van Gool, Bernard Picart said of her "C'est un protige, elle fait l'honneur de son sexe."
