Not many things are known about queen Helena, but if she was Blot-Sweyn's sister she was most likely a pagan like her brother before her marriage. In that case she would have been convinced, willingly or by force, to submit to the Christian faith and convert, receiving the name Helena by her christening. Her daughters were also given names from Christian Europe:
Christina,
Margaret and
Catherine. After the defeat of the pagans, she founded Sweden's first known
nunnery, the Benedictine
Vreta Abbey in
Östergötland, jointly with her spouse, some time between c. 1090 and c. 1100. This is known from a 16th-century paraphrase of a medieval list of donations: "King Inge in Sweden ... with his queen Helena, first founded Vreta Abbey; they bestowed goods and farmsteads to it, as follows: 4
attungs [units] of land in Lilla Vreta, 2 attungs in [Kungs-]Bro, 9 attungs in Brunneby, 4 attungs in Håckla, 2 attungs in Mjölorp." These lands were situated close to Vreta. The royal pair also gave away 2 attungs in Broby, close to
Omberg, also in Östergötland. All these East Geatic donations to the convent form a landmark in Swedish medieval history, since no monastery existed in the kingdom before. Perhaps they belonged to the queen, as a
dowry or as an inheritance after her alleged brother Sweyn. ==Possible ancestry==
