Historical sources, like the Poortersboeken Amsterdam, two tax registers, Notarieel Archief and VOC/WIC-archives have been used in order to create a dataset on 16th and 17th century Amsterdam merchants. Selection and clustering resulted in a subset of merchants originating from the Southern Low Countries. To these three more database-tables, offering information on the social-religious context of the individual merchants, have been added: files F03, F04 and F10. Synthesis of the data in the key-database Prosopography Amsterdam (F06). Data-gathering and selection procedures have been explicitated in Gelderblom's thesis (see in Relation).
