[1] His father was a member of the Council of Brabant and was killed in the early stages of the Dutch Revolt during disturbances in Brussels in 1577/78.

The couple had one son, Frans van Boisschot, Count of Erps, who married Anne Marguerite, countess of Lannoy.

Boisschot died in Brussels on 24 November 1649 and was buried in the Church of Our Blessed Lady of the Sablon.

Boisschot commissioned Anthony van Dyck to paint a portrait of his wife, of which only copies survive.

A portrait of Boisschot auctioned by Sotheby's on 10 July 2014 in London (lot 168) (formerly in the collection of the Earl of Warwick) is believed by some art historians to be the lost original of this painting.
