The Brunwilarensis Monasterii Fundatio names "Helywiga" wife of "Hermanni comitis palatine…cognomente Pusillus", but does not give her origin. Her possible relationship with Ulrich Bishop of Augsburg is based on the Brunwilarensis Monasterii Fundatio naming her son Ezzo as "sancti Udalrici episcopi...consanguineus". Speculation on the precise family relationship is fruitless considering the broad scope of the term “consanguineus”.
The Memorienbuch of Köln St Gereon records the death "II Id Nov" of "Helewich comitissa uxor palatine horum beneficio habemus Grieneswilere". 1
