(O)Fogarty  The sept O'Fogarty was of sufficient importance to give its name to a large territory, viz. Eliogarty, i.e. the southern part of Eile or Ely, the northern being Ely O'Carroll.  Eliogarty is now the name of the barony of Co. Tipperary in which the town of Thurles is situated.  Eliogarty is a phonetic rendering of the Irish Eile ui Fhόgartaigh, the nominative case of the surname being Ó Fόgartaigh.  thogh located outside the area associated with the Dalcassian septs the O'Forgartys are counted as of Dalcassian origin.  Woulfe states that the name is derived from the word fόgartach meaning exiled: the modern Irish word fόgartha does not mean outlawed, but such facile derivations must be accepted with reserve.  The 'Annals of Ulster". under date 1072, desceribe the chief of the sept as O'Fogarty, King of Ely.  In modern times the name is seldom found in English with its prefix O.  The majority of Fogartys come from County Tipperary but their ancient seat, Castle Fogarty, is no longer in their hands.  The most remarkable of these were Malachy O'Fogarty (fl. 1700), born at Castle Fogarty, of the University of Paris, and Archbishop Fogarty (1858-1955), who was for 51 years Bishop of Killaloe: he is best known for his fearless championship of the Irish cause during the "Black and Tan" scourge in the War of Independence.
  The well known surname Gogarty is of cognate origin: it is Mag Fhόgartaigh in Irish.

Fogerty, Gogarty
  The O'Fogarty family is anciently found in Co. Tipperary, Ireland and is considered to be an ancient Irish family.  The family is still to be found in Co. Tipperary, including the area near Thurles, and their former seat of power, 'Castle Fogarty'.
  Eliogarty is the name of the barony in Tipperary named after this family.  In 1072 the Annals of Ulster describe the O'Fogarty chief as 'O'Fogarty, King of Ely'.  They ruled over southern Ely, and O'Carroll ruled over northern Ely (Ely O'Carroll).
  The name in Gaelic was spelled O'Fogartaigh, and has been said to mean exiled, outlawed or expelled.
  The location of Castle Fogarty can be found on the full page map of Tipperary in the 'Complete Book For Tracing Your Irish Ancestors', indexed under 'C' for castle.  One William Fogarty was an adjutant in the Irish American brigades, who resigned in 1863.
  The Fogarty name is well documented in Irish history, and is found in Keatings History.  O'Heerin gives Fogarty as chief of the southern Ely: 'South Ely of well established tributes-Its clans are of the race of Eocaidh Balderg- A country of affluence, abounding in Hazel Woods, It is the land which O'Fogarty obtained.'.
  Most of the name have dropped the "o" prefix long ago, and 61 births of the name were recorded in the 1890 birth index, primarily located in Tipperary and Dublin.
  The name of Gogarty, is presumably of completely separate origins, stemming from the old family of MagFhogartaigh.
