Ancestry
He is descended from Jan van Hoogenhouck Tulleken (1762–1851),[35] a schout-bij-nacht, a Dutch rear-admiral, who was raised to the nobility with the title of Jonkheer (equivalent of a Baronet). As his descendant, this gives Van Tulleken this title as well.
In June 2023, Xand, along with his brother Chris, were the subject of the BBC genealogy programme Who Do You Think You Are?, in which they learned that Jan van Hoogenhouck Tulleken's father, Ambrosius Tulleken, was a wealthy slave trader who had a plantation in Demerara in The Guianas. They also discovered they are of partial Indonesian descent via their Javanese 4x great-grandmother.[35]
