A Swedish born 17th century bishop of Turku,
Johannes Terserus, made a genealogy of the Ostrobothnian clergy families in his diocese, while making a large visitation in the diocese. According to the example of
Johannes Bureus, he wanted to write a genealogy of the "large family in Ostrobothnia" which Bureus mentioned in his manuscript
Om Bura namn och ätt. This "large family" descended from a wealthy farmer in
Teg, Umeå, in
West Bothnia, called
Erik Ångerman, who had a nickname
Sursill (meaning
Surströmming). According to Bureus, Erik or his wife Dordi possibly descended from Bure family, although this remained uncertain. Most of Erik's and Dordi's children moved to Finland. Their many daughters and granddaughters married the progenitors of the well known clergy families, who thus became related with each other. This genealogy was not printed then, but survived as much copied manuscript. In 19th century
Elias Alcenius, pastor of
Lapväärtti, continued the research and published 1850
Genealogia Sursilliana. The next and much enlarged edition by Eero Kojonen,
Sursillin suku, was published in 1971 and sponsored by
Kone Foundation. After that, many corrections and additions to the Sursill genealogy have been published. In Finland, Genealogia Sursilliana meant the beginning of the scholarly genealogy by its lack of prestige. It represented a new type of genealogy compared with genealogies of the nobility at the time. ==Descendants==
