[The following used to be the upper section of Sullivan1. It was moved here to facilitate the expansion of that page.]

BLG1886 reports that "The Irish family of O'Sullivan deduces its descent from Oliol Ollum, King of Munster, who reigned A.D. 125, and whose lineage the Hibernian chronicles trace from Heber Fionn, one of the sons of Milesius." That implies that the following family has a common ancestry with the the family shown on Sullivan1.
