Our History

Settlers from Minnesota – including the first women who would become Sisters – arrived at Union Station in Portland then traveled to Jordan, OR

The Sisters’ first spiritual leader – Father Werner Ruettimann, OSB – offered the first Mass in Jordan, Oregon.

Archbishop William H. Gross, CSsR, met with the Sisters, telling them: “I want you to be my Sisters and help me with my work.”

After a confrontation with the trustees of their settlement, some of the Sisters left Jordan and went to Mt. Angel, Oregon, where they were welcomed by Benedictine monks and Sisters.

Two Sisters moved from Mt. Angel to Mariazell Convent in Sublimity. Others joined them in September and October.

Five Sisters professed vows as Sisters of the Most Precious Blood. Four others were received as novices. Sister Wilhelmina (Emma Bleily) was elected the first Superior General.
