She made great donations to the new religious of the order of Saint-Benoît, installed in the Notre-Dame-de-Bonne-Garde Basilica of Longpont-sur-Orge, a monastery founded by her husband.
According to Gallia Christiana: "She herself went to Cluny to obtain from the abbot a certain number of monks; And she presented to the abbey a golden chalice of thirty ounces and a precious chasuble.”[1] It is reported that Hodierne was working in the construction of the church, and that she went to fetch the water from a distant fountain, which still enjoys the reputation of curing fever.
In order to punish the blacksmith she cursed all the posterity of the hammered men, and swore that any one who came to establish himself at Long Pont would not see the end of the year.
Hodierna married Guy I of Montlhéry and they had seven children: The church of the priory was beautiful, very large, and contained a great number of tombs.
Hodierne was buried there in front of the high altar, under a tomb that reads: Hodieræ inclytcæ omitisshæ erici montis sacrarum harum Ædium fundatricis ossa.
