A Dictionary of Saintly Women/Ida (3)
St. Ida (3), May 5, 17 (Idaberg, Iduberga, Ista, Iste, Itha, Itisberg, Itta, Ydubergue, Ytha, etc.) 7th century. Represented (1) in a group with her husband and daughters, Gertrude (5) and Begga; (2) giving bread to the poor at the door of the monastery. Sometimes called sister of St. Modoald, bishop of Treves. She was a woman of high birth and good fortune, and was the wife of Pepin of Landen, one of the greatest men of the time, both in worldly importance and integrity. Their daughters were the famous SS. Gertrude and Begga, and they had a son, Grimoald, who succeeded his father. St. Ida's fame is lost in that of her younger daughter, St. Gertrude, but it was Ida who, on her husband's death, built the great double monastery of Nivelle on her own estate, and cut off her daughter's hair with her own hands, lest anything should prevent Gertrude from consecrating her life to God there. The mother and daughter gave land and funds to the Irish monks, Foillan and Ultan, at Fosse, or Mors-les-Fossez, to be a perpetual house of hospitality for pilgrims travelling that way. Ida lived five years as a nun under her daughter's rule, assisting her with her advice and care.
Pepin and Ida were buried in the Monastery of Nivelle. Both were called "Blessed" in the Netherlands, and their relics were carried in procession on certain days with those of other saints. Pepin's name was placed in the Litanies by authority of some prelates of the Low Countries, but it has been asserted that the services which were solemnized in their honour at Nivelle previously to the 16th century were not worship, but of the nature of prayers for the dead.
