This database contains information on emigration from a number * of municipalities in Friesland to countries such as the USA and Canada. The groundwork was done by Mrs A. Galema, who conducted extensive archive research for her dissertation. With the help of volunteers, Tresoar subsequently added further data from other municipalities. * At this point in time the database contains information from the following municipalities: Achtkarspelen, Barradeel, Franeker, Harlingen, Menaldumadeel, Smallingerland, Tietjerksteradeel, Oostdongeradeel, Westdongeradeel, Het Bildt, Ferwerderadeel and Wonseradeel.
