On the home page of the entity you will find a link to a more detailed presentation (in Finnish) of the material. The time period of the material extends from the 1540s to the early 20th century.
At the moment families of Alastaro and Mellilä parishes have been published. Over time, the entity will be supplemented by studies of several other parishes and / or villages of Southwest Finland and Tavastia Proper.
Many thanks to Timo Verho for extensive and detailed material. It is worth visiting!
