[5] In 1623 Joannes Cnobbaert was registered as living next to the 'Huys der Professen vande Societeyt IESV, in S. Peeter' in Antwerp.
[9] His presumed mother Maria de Man (Cnobbaert) died on 18 March 1671.
[2] He obtained royal privileges that gave him exclusivity to print in Antwerp books on laws decreed by the counts of Flanders and the so-called suffragia.
[3] He published many works by Jesuit authors, including the April and May volumes of the Bollandists' Acta Sanctorum (1675, 1685).
This may have been related to the location of his printing house next to the seat of the Jesuit Order in Antwerp.
