The Classic in Finnish Genealogy.
Genealogia Sursilliana is an old and large genealogy of Finnish Ostrobothnian families descending from a 16th-century wealthy Swedish farmer, Erik Ångerman, nicknamed Sursill. He had several children, both sons and daughters, most of whom moved to today's Finland. The Sursill genealogy consists of both male and female descendants.
