The name Jordan is common in England but few Irish Jordans are derived from the English source. The Irish Jordans are derived from a Norman family which settled in Connaught in the 12th century. The name is derived from the descendants of Jordan d'Exeter, one of the early Norman leaders. The family became totally hibernicized and the name took on the Gaelic form of McSiurtain. The Barony of Gallen in Mayo was known as McSiurtain's country. The name is also found in Clare where the forms McShurdane and McShurtan are found in the records. It is nowadays commonly anglicized as Jordan. Among prominent current members of the family are Neil Jordan, the Dublin-born author and director of such films as Mona Lisa and The Crying Game, and the current mayor of San Francisco, Frank Jordan who traces his ancestors to Mayo. In the American Revolutionary Army, the officers included Capt. John Jordan of the Penna Artillery Artificers, and Lieutenant William Jordan of the Georgia Continental Brigade.
