[4] Her father was Eberhard I, Count of Zürich[4][5] or possibly Waltfred, Margrave of Verona and Friuli.

[8] Through the marriage of her children, she had close contacts both with the Kingdom of Burgundy (Bertha married King Rudolf II of Burgundy)[9][10] and the royal court of the Ottonians (Ida married the eldest son of Otto the Great, Liudolf).

After the death of her second husband, she retired to the Zürich monastery Felix and Regula, today the Fraumünster.

Adalrich, who built a hermitage on the island of Ufenau in Lake Zurich, is often mentioned as the son of Regelinda, but this has not been proven.

Regelinda built a house there and renovated the existing Martinskapelle (Reginlindenkapelle) and donated the parish church of St. Peter and Paul, which was completed under Adalrich.
