According to the Wikipedia page on his father Tonantius Ferreolus:

http://en.wikipedia.org/wiki/Tonantius_Ferreolus_(senator)

Fidentius, the father of:

St. Ferreolus, Bishop of Uzès (b. 530; succeeded his uncle in 553 ; d. January 4, 581, spent much of the early days of his term converting Jews in his diocese), Feast Day January 4, and

Saint Tarsicia of Rodez (died ca 600), Feast Day January 15 (who lived as a hermit in the Rouergue near Rodez)

Mommarets and Kelley [18] say that Ferreolus Bishop of Uzes was son of a Ferreolus, presumably Ferreolus, Senator of Narbonne above.
