on 19 January 1635 Anselmo de Cocquiel and Daniël Hermans, merchants at Pera near Constantinople (now suburbia), testified at the request of Jacobmijne Ghysbrechts, that the letters they wrote and sent by way of Venice were not answered and that the letters sent from Pera never arrived because of the 'troubels ende grousaeme tyrannie die in ditto Pera sijn omgegaen'. After these summary notes nothing has ever been heard of Jacques Ghijsbrechts. The firm in Antwerp was taken over by his son Peeter (van Hemeldonck 2005).
