Delpher is the largest collection of full-text Dutch-language digitised historical news­papers, books, journals and copy sheets for radio news broadcasts available on a website. This article shows the possibilities of Delpher for doing research on Dutch-Hungarian relations by showing the results of an explorative study on a part of the migration history of one Hungarian family in The Hague. The author shows some very specific parts of the micro history of this family based on the content of newspaper advertisements. These sources were identified by addresses, telephone numbers and unique names.
