St. Gertrude (1), Oct. 18 (Guntrudis, Gontrude). Perhaps 4th century. Sister of SS. Libaria, Manna, Oda, and Susanna, and their brothers, SS. Elphius and Encharius. The names, number, and date of this group vary in different accounts, and they are sometimes confounded with another family of saints. (See Hoylda.) Perhaps this Gertrude is confounded with Gebetrude, abbess of Habend.
