Jan Weenix was born in Amsterdam according to his notice of marriage in 1679 but his date of birth is not exactly known as the baptismal record of this catholic church did not survive.

[6] At least four were sons –Jan Baptista (1680-), Willem Ignatius (1690-1764), Jacobus (1693-), Nicolaes Andreas (1699-1757) – and two were daughters: Sara and Maria Weenix (1697–1774).

In 1697 he painted a portrait of Peter the Great, visiting the Republic to study shipbuilding, science, and the art of fortification building.

After Hearst went bankrupt, the paintings were dispersed; one is in the National Galleries of Scotland in Edinburgh, two are in the Hotel Carlyle in New York, one has been in the Allen Memorial Art Museum since 1953 and one is lost.

[8] Between 1702 and 1712 Weenix was occupied with an important series of twelve large hunting pictures for the Elector Palatine Johann Wilhelm's castle of Bensberg, near Cologne.

[9] Jan Weenix lived most of his life in a house across the Mint Tower and was buried in Nieuwezijds Kapel a nearby catholic church on the Rokin.

Outside the United Kingdom, Jan Weenix is well represented in the galleries of Amsterdam, The Hague, Haarlem, Rotterdam, Berlin, Lisbon and Paris.
