The 1905–06 Football League season was Birmingham Football Club's 14th in the Football League, their 6th in the First Division, their first season under the name "Birmingham", having played as "Small Heath". They finished in seventh place in the 20-team league, they took part in the 1905–06 FA Cup, entering at the first round proper and losing to Newcastle United in the fourth round after a replay. Twenty-three players made at least one appearance in nationally organised first-team competition, there were twelve different goalscorers. Goalkeeper Nat Robinson was ever-present over the 44-match season. Billy Jones was leading scorer with 24 goals; the Coventry Road ground, by surrounded by tightly-packed housing, had more than once proved too small to accommodate those wishing to attend. Against Aston Villa last season, "hundreds of people found the doors closed against them, there were thousands who would not go to the ground in view of the inevitable crush", attendance at the FA Cup fourth-round tie against Newcastle was restricted to 27,000 with "probably 60,000 people anxious to attend".

The landlords had raised the rent, but refused either to sell the freehold or to allow further expansion to the ground, the directors estimated that remaining at Coventry Road was losing the club as much as £2,000 a year in revenue. Club director Harry Morris identified a site three-quarters of a mile nearer the city centre, on the site of a disused brickworks in the Bordesley district, where a new ground could be built; the directors signed construction began.

Not to be confused with the Mac Cearbhaill of Airgíalla. O'Carroll known as Carroll or Carrell, is a Gaelic Irish clan, the most prominent sept of the Ciannachta, their genealogies claim that they are kindred with the Eóganachta, descended paternally from Ailill Aulom. From the Middle Ages until 1552, the family ruled an area within the Kingdom of Munster known as Éile; the last monarch Tiege Caoc O'Carroll regranted to the Tudor Kingdom of Ireland. Notable is the history of the Ó Cearbhaill whose territory, known as Ely O'Carroll in Éile, consisted of the pasture lands of Ballycrinass and Drumcan, extending to the Lake of Leghagh Laghaghirisallive and bounded on the west by the lands called Laghenagarken and on the east adjoining or near to Glencrokin; this was always known as Ely O'Carroll. The mountain land extended from the Laghanagerah to Polle Dowa and in a south easterly direction to the Slieve Bloom Mountains, which are the limits between Ely O'Carroll and Upper Ossory meeting at a village called Garryvoe or Scully's land.

The Ely O'Carroll sept was the most powerful and most famous, but there were at least four other septs, O'Carroll of Oriel in the Dundalk area, O' Carrolls of Ossory in the Carlow/Kilkenny area and two septs in the Kerry area. The prefix "O'" is often dropped in the case of this surname replaced with "Mac". Carvill is another anglicization of the same family name. Of Gaelic Irish descent, the Carrolls have their origins in the ancient kingdom of Éile anglicized Ely, as a branch of the ruling O'Carroll family; the Ely O'Carroll come from counties Tipperary in Ireland. The sept is known as Eile and Clan Cian. One descendant, Charles Carroll of Carrollton, was a wealthy landowner in Maryland and a signer of the Declaration of Independence in 1776, his cousin, Dan Carroll, was a signer of the Constitution. Historic Ely O'Carroll surnames are: Carroll, Bohan/Bowen, Meagher/Maher/Mahar/Mahan, Kelly/Kealy, Corcoran, Nevin, O'Connor. Clan Cian was known as the Cianachta, the Race of Cian, the youngest son, of Olioll Ollum King of Munster, Grandson, of King Eoghan Mor the 1st Mogh Nuadath of Leith Mogha of southern Ireland of the Milesian race of Heber, who contested for supremacy of all Ireland in the second century of the Christian Era.

The Cianachta were led well over 1500 years by a recognized King, High Chief, or Ruling Lord chosen from members of the O’Carroll-Carroll and rival Houses of the noble Septs of Éile In the fifth century the Cianacht Chief, Éile Righ Derg ruled the territory that came to be known as Ely O'Carroll to distinguish the area from other O'Carroll kingdoms and lands. The Kingdom of Éile was located anciently in Ormond in the Counties Tipperary and extending into Offaly, Kilkenny. Cearbhaill Son, of Aeodh, Chief of the Cianachta was King of Éile at the turn of the first millennium; this Cearbhaill, the King of Éile, led the Elyans at the Battle of Clontarf in 1014 with the High King of Ireland, Brian Boru. F. J. "Eile" O'Carroll, the late O'Carroll of Éile O'Carroll created Clan Cian through the Charter of Re-Formation in 1982-1983??as his personal clan for all Cianachta whose families lived within the regions ruled by The O'Carroll of Éile O'Carroll in Ireland as well as to all people who wish to honor their background and the ideals that Clan Cian promotes - Irish culture in all its manifestations and the exploration of expatriate Irish's roots back to Ireland.

The following is quoted from the Ordnance survey letters to King's County 1838 cit. Sir William Betham's Irish Antiquarian Researches. Part I, Pg.95. Sir William Betham was the Ulster King of Arms and can be considered a reliable source as such; the family of O'Carroll, according to the Irish antiquaries, are descended from Kean, the third son of Olioll Olum, King of Munster. Teige, the eldest son of this Kean, was a distinguished warrior, who by killing in battle his three rivals, procured for Cormac Mac Art, King of Ulster, the Monarchy of Ireland. Cormac rewarded him with a grant of land in Connaught called Lurgny Gallen and Culavin, he paying to the King of Connaught and his successors, 150 milch cows in May, he had two sons and Cormac Galeng. Conla, the eldest son, possessed the lands afterwards called Duthec Eile, i.e. the Estate of Eile, from Eile Ridheargs, of which his descendants were styled Kings, there being no other title of honour in use in Ireland before the coming of the English.

Cearbhaill, the twelfth according to some, the 16th in descent according to other authorities, from the above Eile, gave name to the Sept of the O'Carrolls, i.e. the descendants of Cearbhuill. The tenth in descent from him was Teige or Thatheus O'Cearbhuill Boy, King of Eile, who caused the Box of Dimma to be gilt, died about the middle of the 12th century and was succeeded by his son. Maolroona O'Carroll or O'Cearbhaill, King of Eile, was succeeded by his brother. Donald O'Carroll, King of Ely at the coming of the English under Strongbow and from him are descended the Principal houses of this family. Maolroona O'Carroll, whose daughter Grace, or Grania, was married to Ulick Burke, Lord of Clanrickard, was mother of Rickard Sassanagh Burke, the first earl, joined with O'Brien and others against
