 At the same time, in 1252, nuns from Söflingen and Ulm were sent out to found a new convent at Pfullingen (also near Ulm).The relocation to Söflingen was actively assisted by Countess Willibirgis of Helfenstein, a member of the noble family of Dillingen by birth, and finally confirmed when, on 13 January 1258, Hartmann IV, Count of Dillingen, signed a charter donating lands at "Sevelingen", previously owned by the counts of Dillingen, to the nuns in order to found a monastery there.After initially accepting the rule for the Second Order of St Francis of Assisi as laid down by Pope Gregory IX, the nuns accepted the amendments by Pope Innocent IV only to finally follow the rules as promulgated by Pope Urban IV (1261–64).
