Reginlinde of Zürichgau

Reginlinde of Zürichgau (also called Regelinda or Reginlind) was duchess of Swabia by her first marriage, to Burchard II; she was born in 885 or 890 and died on 8 August 958 on the island of Ufenau in Lake Zürich. She is known also as the grandmother of Saint Adelaide, through her daughter Queen Bertha.

Her mother was of the Carolingian line: King Louis the German was her great-⁠granduncle. In 904 she married Burchard II, and together they founded the convent of Saint Margaret at Waldkirch. After Burchard's death she married Hermann I in 926. Through the marriages of her children she had close ties both with the kingdom of Burgundy, for her daughter Bertha married King Rudolf II, and with the Ottonian royal house, for her daughter Ida married Liudolf, eldest son of Otto I. From the marriage of Bertha and Rudolf was born Adelaide, later wife of the emperor Otto the Great.

After the death of her second husband she withdrew to the Zürich convent of Saints Felix and Regula (today the Fraumünster), which she had led since 929 as lay abbess; she is also named lay abbess of Säckingen. On the island of Ufenau, where in the middle of the 10th century a hermitage of the monk Adalrich arose, she built herself a house, restored the chapel of Saint Martin (called Reginlinde's chapel) and endowed the parish church of Saints Peter and Paul, completed in Adalrich's time. She made great gifts to the monastery of Einsiedeln, and through her ties with Otto I the monastery received in 947 the privilege of immunity and free election of the abbot. She died on 8 August 958 on Ufenau and was buried at Einsiedeln. Adalrich is often called her son, but this is not proven.

Our sources describe no liturgical veneration of her, though she is counted among the saints and blessed of the region. No Orthodox synodal canonization is known.
