This dataset contains genealogical information about migrant glassworkers and their families as well as individuals closely related to the glassworks that operated in Estonia from the 17th-19th century as well as glaziers from the 16th century. This dataset is intended for researchers as a basis to build upon and does not contain a complete list of all migrant glassworkers or their family members who have lived in Estonia. The data in this dataset were collected by Monika Reppo using both records kept and digitized at the National Archives of Estonia, Institute of the Estonian Language, and Estonian History Museum as part of a University of Tartu PhD project ‘Glass and its makers in post-medieval Estonia’ from 2017-2023. This dataset consists of a single table which is one of three datasets compiled as part of this PhD project.
