 Later tradition, which is of uncertain provenance, appears to suggest that Secundinus and Auxilius were of Italian origin.Details to this effect are first given in the Irish preface to the "Hymn of Secundinus" as found in some manuscript versions of the "Liber Hymnorum".It states that Secundinus was a son of Restitutus and St Patrick's sister Dar Ercae; in the "Chronicon Scotorum" the latter is named Culmana.
