Sune Sik

According to Olaus Petri, he would have been a younger son of King Sverker I of Sweden and father of Ingrid Ylva.

That Sune Sik made a donation to Vreta Abbey as late as in 1297.

[1] He might have ordered a restoration of a chapel in which he eventually was interred, and later Cistercian tradition may then have turned him into a prince.

[2] Sune Sik, as a son of King Sverker, is counted by other Swedish historians as a person of history and the man buried at Vreta (see photo).

[3][4][5] According to 18th-century Swedish Master of Philosophy Magnus Boræn, Sune was also Duke of Östergötland[6] (at a time when the use of such a title is not known in Sweden[7]).
