This sitters married in 1774. He was the son of Ludovicus van Toulon and (his second wife) Henrica and Machtelina van Toulon, née Verboom. She was the daughter of Hendrik van der Graeff de Vapour and Adriana van der Graeff de Vapour, née de la Barre. Hendrik van der Graeff was ambachtsheer van Wulven from 1724-1779. His daugther (depicted in the present lot) was Vrouwe van Wulven from 1780-1791.
Built in 1296 on the Koedijk in Houten, near Utrecht, Wulven Castle was acquired by the Van der Graeff de Vapour family in 1719. It is depicted in a drawing by Roelant Roghman. In 1827 Wulven was auctioned and bought by Francois Jean, Baron de Wijkerslooth de Weerdesteyn. At some subsequent moment, the castle is thought to have been demolished, as archives describe the location of the castle in 1832 as a garden (O. Wttwaall & J. Smits, 'Wulven', Bijdrage tot de Geschiedenis der Utrechtsche Ridderhofsteden en Heerlijkheden, 1995, pp. 496-9).
An attribution to Christian I van Geelen (1755-1825), who was active as a portraitist in Utrecht, has been suggested.
