An Irish Family History
Now the island of Ireland has been set in the west. As Adam's Paradise stands at the sunrise so Ireland stands at the sunset. And they are alike in the nature of the soil, to wit, as Paradise is without beasts, without a snake, without a lion, without a dragon, without a scorpion, without a mouse, without a frog, so is Ireland in the same manner without any harmful animal, save only the wolf, as sages say. Rawlinson B 512 fol 97 b1 line 14
Irish Origins, History and Genealogy 
The Traceys are referenced a number of times in the Annals:
CS = Chronicon Scotorum (Author: Gearóid Mac Niocaill and William M. Hennessy)
FA= Fragmentary Annals of Ireland (Author: [unknown])
I = Annals of Inisfallen (Author: unknown)
LC = Annals of Loch Cé A.D.1014-1590 (Author: [unknown])
M = Annals of the Four Masters (Author: [unknown])
MCB = MacCarthaigh’s Book (Author: [unknown])
T = Annals of Tigernach (Author: [unknown])
U = The Annals of Ulster (Author: [unknown])
Niell Trassach (or Frassach or Frosach) of the Cenél Eóghain was High King of Ireland 759-765 AD. So-called from certain miraculous showers that fell in his time (a shower of honey, a shower of money, and a shower of blood). After seven years' reign, retired to St. Columb's Monastery at Hye, in Scotland, A.D. 765, where he died in A.D. 773.
The first reference to a Tracey ancestor in the Annals is:
884 AD Treasach, son of Becan, chief of Ui Bairche Maighe, was slain by Aedh, son of Ilguine. Of him Flann, son of Lonan, said: 
A heavy mist upon the province of Breasal, since they slew at the fortaliced Liphe, 
Heavy the groans of Assal, for grief at the loss of Treasach. 
Wearied my mind, moist my countenance, since Treasach lies in death. 
The moan of Oenach Lifi all, and of Leinster to the sea, is the son of Becan.
The following is a link to the manuscript page. [LINK]    
The last reference in the Annals is:
1444 AD Gilla-Michil Ua Tresaigh died.
There appears to be four branches of the Irish Traceys from the ancient genealogies:
1. South Leinster/North East Munster: Laigin tribe of Uí Bairrche (kin to the Gormans). The earliest ancestor is Tressaig or Tressach around 850 AD.
The Traceys of North East Tipperary, Kilkenny, Offaly, Laois, Carlow, Kildare, Wicklow, Louth and Wexford may be presumed to be descended from the Uí Bairrche.
The Uí Bairrche have also been connected to the Uluad, the Uí Echach and Dal Riata of north east Ulster.

2. East Connacht/North West Munster: Fir Bolg Tribe of Sil Anmchadha of Ui Maine (Hy Many) (kin to the Maddens). The earliest ancestor is Treasach around 950 AD.
The Traceys of Galway, Roscommon, North West Tipperary and North Clare may be presumed to be descended from the Sil Anmchadha.
3. Southern Munster: The Eoganacht tribe of Ui Fidegeinti (kin to the Donovans), decended from the house of Heber of the Milesians. The earliest ancestor is Treassach around 650 AD.
The Traceys of Limerick, Waterford, South West Tipperary, Cork, Kerry and South Clare may be presumed to be descended from the Uí Fidgeinti.
4. West Ulster (Fermanagh/Tyrone/Derry /Donegal): Cenel Eoghain decended from the house of Herermon of the Milesians. The earliest ancestor is T[r]easaigh around 600 AD.
The Traceys of Fermanagh, Tyrone, Leitrim, Derry and Donegal may be presumed to be descended from the Cenél Eóghain.
There are also other references to the forename in the ancient genealogies. 
However, the separate tribes may be related. The origin tribe of the Uí Bairrche, the Uí Fidgeinti and the Uí Liatháin may have been the Dáirine. The ancestor of the Uí Bairrche was Dáire Barrach and the ancestor of the Uí Fidgeinti and the Uí Liatháin was Dáre Cherbba. In the Ptolemy map of the 1st century, the Dáirine were located in South Antrim and North Down in the east of Ulster. The Traceys of the Ui Bairrche were dispersed in Leinster and Ulster and possibly Connacht. Some of the Munster Traceys are of the Uí Fidgeinti and Tassys are of the Uí Liatháin.
It would be interesting if a genetic survey could shed some light.

Of interest around this thime period there is a reference to Thrasi of Iceland.
Tracys descended from the Fir Bolg 
The Érainn (earlier Euerni or Iverni) have also been referred to as the Menapii, Bolgi, Builg, Belgae and Firbolgs by certain annalists and historians. The early annalists tell us that Firbolg people survived as distinct tribes well into early historical times. In southern Ireland they may have descended as the Corca Loigde, and other early tribes of Munster, as well as the Osraighe (who are also given a Laigin origin). In east Ulster, they were said to descend as the tribes of the Dál Riata and the Dál Fiatach (aka Ulaid). In Connacht the tribes of the Ui Maine and the Conmaicne are often claimed as their ancestors. In Leinster, they were the Ui Failge, Ui Bairrche and Ui Enechglaiss to mention but a few.
Tracys descended from the Milesians 
The Goídel (Gael or Féni) or Milesians, sons of King Milesius, are said to have come from either northern Spain or southern France to the island of Ireland. Of the Milesians, who invaded the Tuatha De Danann lands, hEber and hEremon divided the land between them - hEremon getting the Northern half of the island, and hEber the Southern. The Northeastern corner was accorded to the children of their lost brother, Ir, and the Southwestern corner to their cousin Lughaid, the son of Ith. Of the Goídel are said to include the various tribes of the Connachta (Northwest, West and Midland) and the Eoghanact (Southwest).
