Listed as Lutherans at the time of the Fall of Antwerp in 1585, the family members seem to have reconverted to Catholicism soon thereafter. The three Wierix brothers gained a reputation for their disorderly conduct as evidenced by a 1587 letter by prominent publisher Christophe Plantin to the Jesuit priest Ferdinand Ximenes in which he complained that whoever wanted to employ the Wierix brothers had to look for them in the taverns, pay their debts and fines and recover their tools, since they would have pawned them. Plantin also wrote that after having worked for a few days the brothers would return to the tavern.
