Bishop of Le Mans; d. August 20, c. 653. Reportedly he was born of a noble family, but little else is known about him before he succeeded bertram in the See of Le Mans, c. 623. As bishop, Hadoindus founded the abbey at Évron (L. H. Cottineau, Répertoire topobibliographique des abbayes et prieurés, 2 v. 1:1089–90) and is said to have aided in the founding of the monastery of St. Lonegisilus (L. H. Cottineau, Répertoire topobibliographique des abbayes et prieurés, 2 v. 2:2769). He attended the councils held at Clichy c. 627 and at Reims from 627 to 630 (Monumenta Germaniae Concilia 1:202;J. D. Mansi, Sacrorum Conciliorum nova et amplissima collectio 10:594); but at the council that met at chalon sur-sÂone in 650, he was represented by Abbot Chagnoaldus (J. D. Mansi, Sacrorum Conciliorum nova et amplissima collectio 10:1194). On Feb. 6, 643, Hadoindus made his last will and testament, in which he designated the church of Le Mans as his heir, leaving it much property, a large portion of which he had received from a wealthy man named Alan. The bishop also requested that he be buried in the church of Saint-Victor. In the ninth century the cult of Hadoindus is clearly attested by the fact that aldric, bishop of Le Mans, exhumed the relics of the holy bishop and placed them in the cathedral church (Gesta Aldrici episcopi Cenomannensis 44).
Feast: Aug. 20 (Diocese of Le Mans).
